Hi, I have having hard time to let cmake configuration detect the zlib header in windows with "Visual Studio 12" generator. My cmake configuration goes like >> Set path, include and lib environment variables to point to zlib headers and libraries. Cmake version is 2.8.12.2 cmake -G "Visual Studio 12" -D LLVM_TARGETS_TO_BUILD:STRING=%TARG% -D

The utils/NewNightlyTest.pl script seems to use LLVMGCCDIR in a way that is inconsistent with the top-level configure script. I would like to fix this but I don't want to break everyone's nightly tests. Can someone review the attached patch to make sure I'm not missing something? The NewNightlyTest.pl script checks the LLVMGCCDIR environment variable and uses it for two

Hello, I am experiencing problems, when trying to assemble these two x86-64 Opcodes "add r64, imm32" "imul r64, r64, imm32" When having the most significant bit set for imm32, for example: "add rax, 0x80000000", "add rax, 0xffffffff", ... "imul rbx, rsi, 0x80000000", "imul rbx, rsi, 0xffffffff", ... The Error Message I receive is the

Hello, LLVM MC blog post <http://blog.llvm.org/2010/04/intro-to-llvm-mc-project.html> explains fairly well how the backend MC project is working. However, it's not clear to me how LLVM converts an assembly file (.s) to an object file. The driver --verbose option is not giving me much information as well. I want to know the flow. Like, What CodeGen phases does this file pass through? Is

Passing an assembly file to clang does not go through any CodeGen phases. It operates entirely in the MC layer. No MachineFunctions will be created. It just runs it through the MCAsmParser. Most of the setup for this is in clang's tools/driver/cc1as_main.cpp in the function ExecuteAssembler ~Craig On Thu, May 10, 2018 at 1:32 PM Soham Sinha via llvm-dev < llvm-dev at lists.llvm.org>

Hi Eric, It's the unsolved problems on the pass-MCTargetOptions-everywhere path that are my main concern with that approach rather than the amount of work. The first problem is that the result of IRObjectFile::CollectAsmUndefinedRefs() depends on the ABI but IRObjectFile doesn't know it. How would you deliver the ABI to IRObjectFile? The second problem is that IRLinker will link

Hi everyone. We're interested in contributing a Hexagon assembler to MC and we're looking for comments on a good way to integrate the grammar in to the infrastructure. We rely on having a robust assembler because we have a large base of developers that write in assembly due to low power requirements for mobile devices. We put in some C-like concepts to make the syntax easier and this

Hello everyone, I'm wrestling with the LLVM unit and regression tests now and would like to discuss some changes to make. I will be preparing patches, but any input/ideas are welcome. I leave "where the tests should run" question out for the scope yet. Let's review what kind of tests we have and how to handle them correctly. We have 3 types of unit and regression tests: 1.)

Is there a simple way to override the target triple used in when running the generic codegen tests? I would expect that passing a value for TARGET_TRIPLE to make, as below, would do it but none of the tests appear to use the target_triplet variable generated in site.exp. > make TESTSUITE=CodeGen/Generic TARGET_TRIPLE=msp430-none-none check -Ken

Hi, Having recently enabled IAS by default for the MIPS O32 ABI, I'm now trying to do the same thing for the MIPS N64 ABI. Unfortunately, it is not currently possible to enable IAS by default for the N64 ABI without also enabling it for the N32 ABI because this information is not reflected in the triple and that's the only information MipsMCAsmInfo has. This would be fine if it N32 was

Hi - attached is a patch to enable building DragonEgg (x86_64) for LLVM3.3 and LLVM3.4. That is, add these changes to the 3.3 release, and it becomes possible to build DragonEgg against a llvm3.4 compiler.

I think a key point to understand is the MCStreamer interface, which has two implementations: one for object-file generation, and one for .s file generation. CodeGen/AsmPrinter can attach to either of these implementations. MCAsmParser will generally attach to the object-file version of MCStreamer. --paulr From: llvm-dev [mailto:llvm-dev-bounces at lists.llvm.org] On Behalf Of Craig Topper via

Still no complete go, doing the tests on i386 failed with some weird sed error: [...] Making Unit/lit.site.cfg for Clang extra tools... sed: lit.tmp: No such file or directory Makefile:61: recipe for target 'Unit/lit.site.cfg' failed gmake[2]: *** [Unit/lit.site.cfg] Error 1 Strangely enough, this does not happen on amd64. Maybe it is some sort of race condition? Did anybody see this
