As a side benefit, lld-link now reports more than one duplicate resource
entry before exiting with an error even if the new flag is not passed.
llvm-svn: 359829
Reduces the error message from:
lld-link: error: failed to parse .res file: duplicate resource: type STRINGTABLE (ID 6)/name ID 3/language 1033, in test1.res and in test2.res
To:
lld-link: error: duplicate resource: type STRINGTABLE (ID 6)/name ID 3/language 1033, in test1.res and in test2.res
Make sure every error message emitted by cvtres contains the name of at
least one ".res" file, so that removing the "failed to parse .res file"
string doesn't lose information.

For well-known type IDs, include the name of the type.
To not duplicate the ID->name map, make llvm-readobj call this new
function as well. It has slightly different output, so this also
requires updating a few tests.

If two .res files contain the same resource, cvtres.exe (and hence
link.exe) reject the input with this message:
CVTRES : fatal error CVT1100: duplicate resource. type:STRING, name:101, language:0x0409
LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt
llvm-cvtres (and lld-link) used to silently pick one of the duplicate
resources instead. This patch makes them report an error as well.
We slightly improve on cvtres by printing the name of two .res files
containing duplicate entries as well.

Before, there was an IsData parameter. Now, there are two different
functions for data nodes and ID nodes. No behavior change, needed for a
follow-up change to make two data nodes (but not two ID nodes) with the
same ID an error.
For consistency, rename another addChild() overload to addNameChild().

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
The idea is that it would replace
(non-Writable)MemoryBuffer::getNewMemBuffer, which is quite useless
unless you const_cast its contents to write to it (which all (both)
callers of this function were doing). This patch also fixes one of the usages in
COFFWriter. After fixing the other usage in clang, I plan to delete the old
function.

Summary:
We were using sprintf(..., "$R06X", <some uint32_t>) to create strings
that are expected to be exactly length 8, but this results in longer
strings if the uint32_t is greater than 0xffffff. This change modifies
the behavior as follows:
- Uses the loop counter instead of the data offset. This gives us
sequential symbol names, avoiding collisions as much as possible.
- Masks the value to 0xffffff to avoid generating names longer than 8
bytes.
- Uses formatv instead of sprintf.
Fixes PR35581.

Revert "Revert "Revert "Revert "Replace trivial use of external rc.exe by writing our own .res file.""""
This reverts commit 61a90a67ed54a1f0dfeab457b65abffa129569e4.
The patches were intially reverted because they were causing a failure
on CrWinClangLLD. Unfortunately, this was done haphazardly and didn't
compile, so the revert was reverted again quickly to fix this. One that
was done, the revert of the revert was itself reverted. This allowed me
to finally fix the actual bug in r307452. This patch re-enables the
code path that had originally been causing the bug, now that it (should)
be fixed.
llvm-svn: 307460
Summary:
The original cvtres.exe sets the high bit when an identifier offset
points to a string. Even though this is not mentioned in the spec, and
in fact does not seem to cause errors with most cases, for some reason
this causes a failure in Chromium where the new resource file is not
verified as a new version. This patch sets this high bit flag, and also
adds a test case to check that the output of our library is always
identical to original cvtres.

This revert was originally done because the integrations of the new
WindowsResource library into LLD was causing error in chromium, due to
bugs in how resource sections were handled. These bugs were fixed,
meaning that the features may be reintegrated.

This reverts commit d4c7e9fc63c10dbab0c30186ef8575474a704496.
This is done in order to address the failure of CrWinClangLLD etc. bots.
These throw an error of "side-by-side configuration is incorrect" during
compilation, which sounds suspiciously related to these manifest
changes.

This reverts commit 71fe8ef283a9dab9a3f21432c98466cbc23990d1.
llvm-svn: 306618
This patch removes the dependency on the external rc.exe tool by writing
a simple .res file using our own library. In this patch I also added an
explicit definition for the .res file magic. Furthermore, I added a
unittest for embeded manifests and fixed a bug exposed by the test.
llvm-svn: 306311
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.
