use a SUB instruction instead of an ADD, because -128 can be
encoded in an 8-bit signed immediate field, while +128 can't be.
This avoids the need for a 32-bit immediate field in this case.
A similar optimization applies to 64-bit adds with 0x80000000,
with the 32-bit signed immediate field.
To support this, teach tablegen how to handle 64-bit constants.

runnable on the build machine.
There are a few bits that need built for the build environment (TableGen).
This patch builds those bits, and the associated libraries, for the build
environment as well as the (usual) host environment.
Thanks to Eric C. and Devang P. for pre-commit review.

put into the CPP.Defines variable. Seems the convention was corrupted with
various changes made. It is important to get command line parameters into the
right variable because things like llvm-config and sub-makefiles depend on it.
llvm-svn: 38486
--enable-expensive-checks allows the developer to enable runtime
checking that can greatly increase compile time. Currently it only
turns on _GLIBCXX_DEBUG. Other expensive debugging checks added later
should be controlled by this configure option.
This patch also updates llvm-config with a --cppflags option to inform
llvm-gcc how to build itself so that it is compatible with an llvm that
was built with _GLIBCXX_DEBUG.

Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

"clean" target item. This gets around having the built sources disappear
when only one build mode wants to be cleaned. With the "clean-all" target,
all build modes are cleaned so it also makes sense to clean out the built
sources at that point.

a directory's Makefile will prevent the build products from that directory
from being installed. This is useful for tools and libraries that are
only useful as part of the build process.

specify its own libraries in conjunction with LINK_COMPONENTS. llvm-stacker

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

will compute a locally wrong numbering for the intrinsics. This fixes a
nasty issue where the x86 backend started miscompiling stuff in a 'cvs up'd
build after the altivec intrinsics were added.

Close out this long standing bug by removing the remaining overloaded
virtual functions in LLVM. The -Woverloaded-virtual option is now turned on.
llvm-svn: 29934
Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:
DEBUG BUILD RELEASE BUILD
before after delta before after delta
lib 162,328K 157,616K 4,712 17,864K 16,416K 1,448K
bin 571,444K 557,156K 14,288 63,296K 56,996K 6,300K
Debug Improvement: 19,000K (2.59%)
Release Improvement: 7,748K (9.55%)
llvm-svn: 29882
and a handler, which would produce errors like:
terminate called after throwing an instance of 'std::string'
we must comment out setting -fno-exceptions until PR797 is completely
fixed. Once libraries like lib/System and lib/Support are exception free,
we can turn it back on.
llvm-svn: 29768
1. Actually turn on -fno-exceptions in libraries that do not have the
REQUIRES_EH option in their Makefile. The following library file size
savings were made (DEBUG):
libLLVMDataStructure.a 525K
libLLVMCore.a 380K
libLLVMCodeGen.a 350K
libLLVMTransformUtils.a 305K
libLLVMScalarOpts.a 270K
libLLVMAnalysis.a 247K
libLLVMSelectionDAG.a 233K
libLLVMipo.a 175K
LLVMX86.o 123K
LLVMPPC.o 81K
libLLVMipa.a 17K
TOTAL 2,706K
Note that the savings is actually a little larger than this because
I didn't count any of the libraries that had small changes.
2. Remove REQUIRES_EH from the AsmParser library as it is now exception
free. This resulted in a nearly 78K drop in the size of the debug
library for AsmParser.
llvm-svn: 29767
1. Change the usage of LOADABLE_MODULE so that it implies all the things
necessary to make a loadable module. This reduces the user's burdern to
get a loadable module correctly built.
2. Document the usage of LOADABLE_MODULE in the MakefileGuide
3. Adjust the makefile for lib/Transforms/Hello to use the new specification
for building loadable modules
4. Adjust the sample project to not attempt to build a shared library for
its little library. This was just wasteful and not instructive at all.
llvm-svn: 29551
Turn -pedantic and -Wno-long-long compile flags on by default. In a few
places, avoid the warnings by removing these options in the local makefile.
One notable exception: lib/Target/CBackend/Writer.cpp. These warnings are
left on as a reminder to developers to clean them up.
llvm-svn: 28614
1. Remove the LLVM_DO_NOT_BUILD feature (not needed any more)
2. Ensure that lib/VMCore gets built first. This needs to be done because
VMCore now uses tblgen to generate the Intrinsics header which are
needed in other libraries. In parallel builds, this can cause problems.

depend on LLVM libraries) come first on the command line and can thus be
resolved by the LLVM libraries that appear later.

a -L option to gccld whenever we're building a bytecode module or archive.
This gets around the "Cannot find library 'crtend'" warning messages.

1. Don't force debug builds to have assertion checking turned on always.
Let the default (on) be taken, or overridden by the command line
2. Create two new BuildModes based on assertion checking: Release+Assert
and Debug-Assert.
3. Ensure that when building a distribution we get a release build with
assertions enabled, regardless of the tree's configuration.
4. (unrelated) Fix library name generation for llvm-config usage.
llvm-svn: 27488
This facility allows LLVMLIBS to be specified with something like:
LLVMLIBS = config --libs jit
instead of:
LLVMLIBS = JIT
with the same effect. However, the llvm-config utility is much more versatile
than the single keyword approach. Note that "config" is the keyword after
which any arguments to llvm-config are allowed. When llvm-config is tested
and working well, we'll start using this and drop support for the JIT
keyword.
llvm-svn: 27057

want to copy the files when the .cpp file changes, we want to copy them
to the .cvs versions when the .l/.y file change (like the comments even say).
This avoids having bogus changes show up in diffs.
llvm-svn: 26229
* Make runtimes and projects build with the new front-end by not relying on
'llvm-gcc -c' to build a .bc file. Instead, use llvm-gcc -S -emit-llvm,
then an explicit invocation of gccas. Also, don't use llvm-gcc to link
.bc files together, use gccld directly.
llvm-svn: 25707
1. When srcdir == objdir have "spotless" say that it isn't supported in
that mode rather than just let make say "no such target"
2. Minor doc cleanups
3. Fix the double rebuild problem with yacc files. A missing dependency
caused parallel builds to skip building the .cpp file after the .cpp
file was regenerated by bison.
llvm-svn: 24924
* Add --enable-debug-runtime option, defaults to disabled
* Pass the new config var, DEBUG_RUNTIME, to Makefiles
* Don't use -Wa,-strip-debug if debug-runtime is enabled

into the LLVMAnalysis library.
This allows LLVMTranform and LLVMTransformUtils to be archives and linked
with LLVMAnalysis.a, which provides any missing definitions.
llvm-svn: 24036
SparcV9 JIT.
2. Make LLVMTransformUtils a relinked object file and always link it before
LLVMAnalysis.a. These two libraries have circular dependencies on each
other which creates problem when building the SparcV9 JIT. This change
fixes the dependency on all platforms problems with a minimum of fuss.
llvm-svn: 24023
pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.
llvm-svn: 23888
These changes modify the makefiles so that the output of flex and bison are
placed in the SRC directory, not the OBJ directory. It is intended that they
be checked in as any other LLVM source so that platforms without convenient
access to flex/bison can be compiled. From now on, if you change a .y or
.l file you *must* also commit the generated .cpp and .h files.
llvm-svn: 23115
Move the implementation of the fix from Makefile.rules to Makefile. This
ensures that it is only checked on a top-level rebuild, and not in every
single subdirectory. This removes some annoying messages from the build and
numerous executions of config.status if the .in file changes but not
substantively enough to cause the .h file to be modified by config.status.
llvm-svn: 23039
Make any header files that are automatically generated be preconditions of
the compilation. This ensures that if a *.h.in file is changed then its
corresponding *.h file gets updated on the next rebuild. Note that this can
lead to confusing (but correct) results if the *.h.in file changed
unsubstantially so that autoheader doesn't update the *.h file. In that case,
manually touch the *.h file in question to restore order. Moral of the story,
if you're going to "touch" a *.in file then modify it substantially.
llvm-svn: 23006
1. Allow DIST_CHECK_CONFIG_OPTION to specify a set of options to be passed
to the configure script during the dist-check target. This allows things
to be passed down on a project basis so the configure doesn't fail.
2. Use the tar | (cd ; tar ) idiom to copy files which is more flexible
than using the cp command. THis allows us to exclude CVS .svn
directories at source rather than stripping them out of the tar ball.
llvm-svn: 22166
llvm archive or re-linked libraries:
1. Permit the "JIT" special keyword on LLVMLIBS to be recognized when
building a library, not just for building tools
2. If LINK_LIBS_IN_SHARED is set, the LLVMLIBS and USEDLIBS can be specified
when linking a shared library and the libraries listed will be
incorported into the shared library. THis is only used when the
SHARED_LIBRARY variable is set.
llvm-svn: 22127
* Consolidate all "install" usage to the install program/script found by
autoconf which includes the autoconf/install-sh script if necessary
* Change Makefile.rules to not use the -D flag to install but use the
MKDIR command as necessary.
* Change Makefile.rules to differentiate between installation of executable
files and regular data files to get the permission modes correct.
llvm-svn: 20294
* Make it possible to have the Install program run in verbose mode when
the TOOL_VERBOSE=1 option is set
* Ensure non-executable installed files do not install with execute perms.
llvm-svn: 20214
When llvm-gcc is not available, bypass rules for Modules and Bytecode
Libraries that require llvm-gcc and emit instead a warning that llvm-gcc
is not available. This permits "make LLVMGCC=" to build LLVM completely
without error and provides warnings about the modules and bc libs that
could not be constructed.
llvm-svn: 20185
passes the -module option on the libtool command line to ensure that the
shared library being built can be dlopened and dlsym can work on that
module. LOADABLE_MODULE should be sent only in conjunction with the
SHARED_LIBRARY directive. It should generally be used for any module that
is intended to be the target of an LLVM -load option. Note that loadable
modules will not have the lib prefix but otherwise look like shared
libraries. This is per the libtool recommendations and prevents these
special shared libraries from being linked in via -l option to the linker.
llvm-svn: 19454
Reverting the quote patch. For some reason, this breaks the building of
llvm/runtime (the shell doesn't like it for some reason). I might play
with it to see if I can get the quotes done in such a way that the shell
like it, but no promises.
llvm-svn: 19275

Many thanks to Duraid Madina for doing the heavy lifting on the analysis
of this problem.
llvm-svn: 19256
* When reconfiguring, make sure the config.cache file is blown away so that
its (old) values don't short-circuit doing the tests. When a reconfigure
is done, it should be done from scratch, without the cache.
* For dist-check, don't pass --with-llvmgccdir any more because configure
doesn't have this option any more.
llvm-svn: 19126
* Cleanup LLVMGCXX and LLVMGCC by providing LLVMGXXWITHPATH and LLVMGCCWITHPATH
variables that add the $(LLVMToolDir) to the path so the CFE tools can find
the right LLVM tools they depend on.
* Standardize the name of a variable: cferuntime_libdir -> CFERuntimeLibDir
llvm-svn: 19095
* Convert "cmp" usage to $(CMP)
* Convert "cp" usage to $(CP)
* Fix some build messages to reflect what's actually going on
* Add a "reconfigure" target for forcing a reconfigure. Helps with testing
things like Chris's recent changes.
llvm-svn: 18991
files that USE the .inc file unless the contents of the .inc file changes.
This should fix the problem where reconfiguring causes all targets to be
completely rebuilt (because config.h is usually modified, causing libsystem
to be rebuilt, causing tblgen to be rebuilt, causing .inc files to be
rebuilt, causing .o files to be rebuilt).
This patch also checks in a gross hack where .o files now explicitly depend
on $(BUILT_SOURCES), to avoid problems where the .inc files are not completely
generated before the .o files start to compile.
llvm-svn: 18986
to BUILD_OBJ_SRC. This will save the config.status and mklib files, then
wipe out the BUILD_OBJ_ROOT, copy back config.status and mklib, and then
run config.status to regenerate the makefiles. This target gives you a
completely clean/fresh BUILD_OBJ_ROOT.

* Implement the FAKE_SOURCES feature for GCCLibraries/crtend \
* Search for distribution files >first< in srcdir and >second< in objdir \

* Make dist-check run correctly in parallel builds \
* Wrap lines to 80 cols \
* Standardize variable names
llvm-svn: 18504
Change construction of bytecode libraries from producing a single bytecode
file to producing a library containing bytecode files. This gets around the
problem of multiple symbol definitions in the linker if something like
-lc -lc is attempted on the command line. Previously this happened because
the linker would find libc.bc as a "library". It will now find libc.a which
it can simply search for missing symbols instead of linking in wholesale.
llvm-svn: 18425
* Get rid of appending -lbz2 and -lz to ExtraLibs now that we don't need
them any more.
* Fix the dist-check target so that EXTRA_DIST can be defined AFTER the
include of Makefile.common. This is needed because Makefile.common
provides variable definitions that may need to be used in computing the
value of EXTRA_DIST.
* Clean up some "distdir" target output.
llvm-svn: 18329
Tools and libraries will be built into $(BUILD_OBJ_ROOT)/$(BuildMode)/bin and \
$(BUILD_OBJ_ROOT)/$(BuildMode)/lib, respectively. Furthermore, the example \
programs will go in $(BUILD_OBJ_ROOT)/$(BuildMode)/examples to keep them \
separate from the tools and hopefully out of the PATH. Install targets \
have not changed.
llvm-svn: 17953
* Don't include Makefile.rules in set of preconditions, it never has to be
copied to objdir.
* Enable the "update makefile first before executing targets" feature in
gnu make by *not* using a full path to the Makefile in the rule.
llvm-svn: 17920
$(ObjDir) and clean out all build modes (Debug, Release, Profile) in
addition to the normal "clean" rules.
* Fix "clean" problems with Lex/Yacc so all files are remove properly.
* Ensure errors from "rm" don't thwart the uninstall and clean targets.
llvm-svn: 17433
sub-makes and recursively append causing huge command lines and incorrect
compilation results.
Also, fix the printvars target to align its output and ensure that the
contents of variables can't get interpreted by the shell.
llvm-svn: 17348
* Move rules that build directories earlier in the file so that they are
always built before the things that depend on them. This enables a
parallel "dist-check" target.
* Fix use of TOOLLINKOPTS and TOOLLINKOPTSB (thanks to Henrik Bach)
* Standardize the output - some scripts using plain echo instead of $(ECHO)
llvm-svn: 17318
* Ensure that BUILT_SOURCES depends on OBJ_DIR/Makefile so that they do not
get built before the Makefile is updated.
* Fix build script for yacc & lex files by stopping it from thwarting the
dependencies on the file. If the .y file changes, it needs to be rebuilt.
This also cleans up the problem with llvmAsmParser ALWAYS rebuilding its
Yacc files just to throw them away because there's no change.
llvm-svn: 17288
* Force preconditions to be met FIRST
* Fix dist-check dependency
* Add some variables to the printvars target
* Automatically update Makefile.* as well as just Makefile

tarball.
* Fix bugs in the "dist" target (a precursor to dist-check).
* Correct the implementation of the "install" targets so that they ensure
the installation directories are created before attmpting to install
directories in them.
* Reduce the verbosity of the output of the makefile system
* Ensure output includes the configuration whenever libraries or tools are
built, installed, or uninstalled.
llvm-svn: 17250
* "dist" target now builds tar.gz, tar.bz2, and zip files suitable for
distribution. "dist" can only be run from $(BUILD_OBJ_ROOT) and implies
a "check".
* made the preconditions not do a recursive make and ensured that they are
executed sequentially.
* made the messages output by the makefile be prefixed with "llvm" and the
make level (e.g. llvm[1]: ) in the same way that make does so that the
messages are uniform and more readable.
* Fixed the tags target so that tags depends on TAGS which contains the
rules to build a file named TAGS
* Implemented the EXTRA_DIST feature in a few directories to make sure it
works.
llvm-svn: 17210
* Fixed the install target to install files correctly
* Implemented the uninstall target to remove files from install dirs
* Isolated the top level targets (dist, dist-check, dist-clean, tags) so
they only run/exist from the top level directory
* Put if/endif gaurds around potentially dangerous $(RM) commands.
* Implemented place-holder rules for distribution targets to just say that
they aren't implemented yet.
* Implemented tags target in Makefile.rules so all projects can use it
* Made a pony for resistor
llvm-svn: 17202
* Fix parallel build problem on generated dependency files
* Fix rule confusion between .a and .la libraries so that parallel builds
don't get confused on who is building which .o and which library it is
going into.
* Fix dependency inclusion to only include C/C++ dependency files because
other types of sources won't have dependencies auto generated.
* Change "Source" to "SOURCES" for naming consistency
* Update parallel build rules for new recursive targets
* Implement EXPERIMENTAL_DIRS (failure allowed) feature
* Implement -local version of targets (all-local, clean-local, etc)
* Implement recursive targets in terms of their local counterparts
* Clarify names of some internal variables
* Move documentation to docs/MakefileGuide.html
* Clean up commentary
llvm-svn: 17192
* Use LLVM_SRC_ROOT as the anchor for the Target.td file
* Use MFLAGS instead of MAKEFLAGS for recursive makes so we don't try
to build a target "w" or "s" mysteriously.

the existence of that directory, and add a rule for creating it if

llvm-svn: 10946
Directory targets no longer check for existance of the directory in the
object tree; if the Makefile doesn't exist, we will re-create the directory.
This seems to be a pretty good assumption and saves us from checking
directory existance each time.

Added Makefile.spec to the list of files to copy to the object directory.
Moved the configuration of $SourceDir to Makefile.config and corrected the

llvm-svn: 8475
much cleaner and easier.
Labeled .td as a suffix for tblgen files in Makefile.rules.
Modified build rules so that source files generated during the build are placed
in the build directory and not the source directory (and not in a Debug
directory). This makes the system cleaner and allows us to have a read-only
source tree.
llvm-svn: 8424
Moved Makefile.common to Makefile.rules. This makes project Makefiles easier
to support, and allows for easier overriding of default configuration values
that used to be in Makefile.common.
Modified Makefile.config.in to determine paths for directories (like
LLVM_SRC_ROOT) and to use the pwd binary as opposed to the shell builtin (this
works better for symbolic links).
