* Add CAN_DLOPEN_SELF so we can determine if dlopen(0) will open the
program or not.
* Correct a warning messages to be a little more specific on what it checks
llvm-svn: 19184
SysConf abstraction was pointless because it had a single function in it that
pertained only to the current process. So merge it into the Process abstraction
and remove the files completely.
llvm-svn: 19149
* Make sure all headers used by lib/System have checks
* Use "standard" autoconf checks for certain problematic headers
For PR432:
* Resurrect --with-llvmgccdir so a specific llvm-gcc/llvm-g++ installation
can be specified.
llvm-svn: 19142
Create new variables LLVM_ON_UNIX and LLVM_ON_WIN32 so we can start getting
rid of reliance upon a symbolic link to switch implementations in lib/System
llvm-svn: 19131
* Add GetMallocUsage as a wrapper around mallinfo()
* Add GetTotalMemoryUsage to get approximate RSS size
* Add GetTimeUsage to get elapsed/system/user time
llvm-svn: 19051
Incorporate the abilities of RunPRogramWithTimeout into
sys::Program::ExecuteAndWait so that redirection and a timeout are optionally
supported.
llvm-svn: 19039
Replace RunProgramWithTimeout with an inline function that calls
sys::Program::ExecuteAndWait. This is now just a convenience function.
llvm-svn: 19037
* Make the OutputC and OutputAsm functions work with sys::Path for the output
file name instead of using std::string.
* Get rid of extraneous "toString" calls.
* Change "removeFile" to sys::Path::destroyFile()
llvm-svn: 19000
* Remove the "removeFile" function, now implemented by the
sys::Path::destroyFile method.
* Make the FileRemove work with a sys::Path instead of a std::string
llvm-svn: 18999
createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.
llvm-svn: 18961
* Fix implementation and documentation about LLVMGCCDIR/bytecode-libs
* Add the makeUnique method, replacement for getUniqueFilename in Support.
* Add the sys::CopyFile function, replacement for CopyFile in Support.
* Move GetLLVMConfigDir() into generic code area since its generic.
llvm-svn: 18947
Remove AllocateRWXMemory as it is not used any more in LLVM. The function
has been replaced with sys::Memory::AllocateRWX several months ago.
llvm-svn: 18912
Remove the MakeFileReadable and MakeFileExecutable functions which are no
longer present in LLVM. They have been replaced with the sys::Path methods
makeReadable and makeExecutable, respectively.
llvm-svn: 18910
Implement three new functions to allow setting access/permission bits on
the file referenced by a path. The makeReadable and makeExecutable methods
replace the FileUtilities MakeFileReadable and MakeFileExecutable
functions. The makeWritable function is new and provided for consistency
since Path has a writable() method.
llvm-svn: 18907
The ReadFileIntoAddressSpace and UnmapFileFromAddressSpace functions are no
longer used by LLVM. Remove them. Replacement functionality for both
functions is now encapsulated in the sys::MappedFile class.
llvm-svn: 18903
The getFileTimestamp and getFileSize functions have been removed from \
FileUtilities.{h,cpp}. They are replaced by Path::getTimestamp and \
Path::getSize,respectively.
llvm-svn: 18892
* Consolidate path retrieval into just two methods. \
* Add FindLibrary as a convenience function. \
* Add isDynamicLibrary for testing for dynamic libs. \
* Make toString constant and reference clean.
llvm-svn: 18847
library into the address space permanently. SearchForAddressOfSymbol looks
in all previously permanently loaded libraries and any currently open
libraries for a symbol, instead of just one library like GetAddressOfSymbol
llvm-svn: 18354
fact that all ExternalSymbols are actually string literals with static storage.
Thus we don't have to do anything special to hold them and we certainly don't
have to copy string data around.
llvm-svn: 18007
