Some forms have sizes that depend on the DWARF version, DWARF format
(32/64-bit), or the size of an address. Collect these into a struct
to simplify passing them around. Require callers to provide one when
they query a form's size.

As noted on PR32585, the change in D29780/rL295325 resulted in calls to Rand32() (values 0 -> 0xFFFFFFFF) but the min()/max() operators indicated it would be (0 -> 0x7FFFF).
This patch changes the random operator to call Rand() instead which does respect the 0 -> 0x7FFFF range and asserts that the value is in range as well.

We added the initilization of disassembler passes in r306208 with the goal to
bring bugpoint in line with 'opt'. However, 'opt' does itself not initialize
dissassembler passes. As our goal was consistency, we drop the initialization
of dissassembler passes again from bugpoint.
Thanks to Chandler for pointing this out!
llvm-svn: 306275
This patch links LLVM back-ends into bugpoint the same way they are already
available in 'opt' and 'clang'. This resolves an inconsistency that allowed the
use of LLVM backends in loadable modules that run in 'opt', but that would
prevent the debugging of these modules with bugpoint due to unavailable /
unresolved symbols.
For e.g. In D31859, Polly requires the NVPTX back-end.

We would return an error in getVaPtr if the RVA table being dumped was
the last data in the .rdata section. Avoid the issue by subtracting one
from the offset and adding it back to get an open interval again.

This is useful when you want to look at a specific chunk of a
stream or look for discontinuities, and you need to know the
list of blocks occupied by a stream.
llvm-svn: 306150
This patch dumps the raw bytes of the pdb name map which contains
the mapping of stream name to stream index for the string table
and other reserved streams.
llvm-svn: 306148
Normally we can only make sense of the content of a PDB in terms
of streams and blocks, but in some cases it may be useful to dump
bytes at a specific absolute file offset. For example, if you
know that some interesting data is at a particular location and
you want to see some surrounding data.
llvm-svn: 306146
The goal here is to make it possible to display absolute
file offsets when dumping byets from an MSF. The problem is
that when dumping bytes from an MSF, often the bytes will
cross a block boundary and encounter a discontinuity. We
can't use the normal formatBinary() function for this because
this would just treat the sequence as entirely ascending, and
not account out-of-order blocks.
This patch adds a formatMsfData() function to our printer, and
then uses this function to improve the output of the -stream-data
command line option for dumping bytes from a particular stream.
Test coverage is also expanded to make sure to include all possible
scenarios of offsets, sizes, and crossing block boundaries.

This idea originally came about when I was doing some deep
investigation of why certain bytes in a PDB that we round-tripped
differed from their original bytes in the source PDB. I found
myself having to hack up the code in many places to dump the
bytes of this substream, or that record. It would be nice if
we could just do this for every possible stream, substream,
debug chunk type, etc.
It doesn't make sense to put this under dump because there's just
so many options that would detract from the more common use case
of just dumping deserialized records. So making a new subcommand
seems like the most logical course of action. In doing so, we
already have two command line options that are suitable for this
new subcommand, so start out by moving them there.
llvm-svn: 306056
Now you run llvm-pdbutil dump <options>. This is a followup
after having renamed the tool, whereas before raw was obviously
just the style of dumping, whereas now "dump" is the action to
perform with the "util".

This includes the safe SEH tables and the control flow guard function
table. LLD will emit the guard table soon, and I need a tool that dumps
them for testing.

With PR33517, it became apparent that symbol table creation can fail
when presented with malformed inputs. This patch makes that sort of
error detectable, so llvm-cov etc. can fail more gracefully.
Specifically, we now check that function names within the symbol table
aren't empty.
Testing: check-{llvm,clang,profile}, some unit test updates.

in the base address.
Without this Mach-O files, like 64-bit executables, don’t have the correct

In order to reduce swift binary sizes, Apple is now stripping swift symbols
from the nlist symbol table. llvm-nm currently only looks at the nlist symbol
table and misses symbols that are present in dyld info. This makes it hard to
know the set of symbols for a binary using just llvm-nm. Unless you know to
run llvm-objdump -exports-trie that can output the exported symbols in the dyld
info from the export trie, which does so but in a different format.
Also moving forward the time may come a when a fully linked Mach-O file that
uses dyld will no longer have an nlist symbol table to avoid duplicating the
symbol information.
This change adds three flags to llvm-nm, -add-dyldinfo, -no-dyldinfo, and
-dyldinfo-only.
The first, -add-dyldinfo, has the same effect as when the new bit in the Mach-O
header, MH_NLIST_OUTOFSYNC_WITH_DYLDINFO, appears in a binary. In that it
looks through the dyld info from the export trie and adds symbols to be printed
that are not already in its internal SymbolList variable. The -no-dyldinfo
option turns this behavior off.
The -dyldinfo-only option only looks at the dyld information and recreates the
symbol table from the dyld info from the export trie and binding information.
As if it the Mach-O file had no nlist symbol table.
Also fixed a few bugs with Mach-O N_INDR symbols not correctly printing the
indirect name, or in the same format as the old nm-classic program.

In this patch, I flip the switch in DriverUtils from using the external
cvtres.exe tool to using the Windows Resource library in llvm.
I also fixed a bug where .rsrc sections were marked as discardable
memory and therefore were placed in the wrong order in the final PE.
Furthermore, I modified WindowsResource to write the coff directly to a
memory buffer instead of to file, also had it use the machine types
already declared in COFF.h instead creating my own enum.
Finally, I flipped the switch to allow all unit tests that had
previously run only on windows due to a winres dependency to run
cross-platform.
