similar to: [LLVMdev] llvm-gcc

Hi, I'm new to LLVM. I need a confirmation about a little understanding about the LLVM When we use llvm-gcc without using -C, llvm tools and optimizations are not used at all. By the way, Does llvmc works on the bitcode format? Therefore, all optimizations of LLVM is on bitcode format described in LLVM Language Reference Manual ? Thanks for clarification.

I'd suggest disabling bootstrapping. That was going to be my guess (PR1557 I think it is). If I get some spare cycles in the

Thanks. I wonder if we could use .bc file generated by X-86 llvm-gcc to feed SPARC llvm in some cases. -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Nathan Keynes Sent: Thursday, June 26, 2008 5:18 AM To: LLVM Developers Mailing List Subject: Re: [LLVMdev] Compile llvm-gcc-4.2 on sparc-sun-solaris2.10 On 20/06/2008, at 3:22

Greetings everybody! In my quest to attract more users to llvmc, I've added support for compilation via the Clang front-end (previously, only llvm-gcc was supported). This is enabled with the '-clang' switch; basically, you can now just alias 'ccc' to 'llvmc -clang' and get the same functionality. Examples: Compile via Clang: $ llvmc -clang test.c

To answer my own question. The problem is that Solaris ships with very old tools, and llvmc was generating assembler that worked with a fresh (gcc-4.5) compile & install. I had them handy, just further down the path. Hopefully anyone with the same problem can find this in the archive. Thanks everyone.

So my

Hi, I built LLVM + Clang on Mac OS X and ran make check. I get the following result summary: Failing Tests (11): LLVM :: LLVMC/C++/dash-x.cpp LLVM :: LLVMC/C++/hello.cpp LLVM :: LLVMC/C++/just-compile.cpp LLVM :: LLVMC/C++/together.cpp LLVM :: LLVMC/C++/unknown_suffix.unk LLVM :: LLVMC/C/hello.c LLVM :: LLVMC/C/opt-test.c LLVM :: LLVMC/C/sink.c LLVM ::

According to the FAQ llvmc is considered experimental/unsupported. But FWIW, here's an issue I found while trying to use it on 32 bit x86 systems. tools/llvmc/plugins/Base/Base.td hardcodes the -relocation-model=pic option into invocations of llc: def llc : Tool< [(in_language "llvm-bitcode"), (out_language "assembler"), (output_suffix "s"), (cmd_line

Hi all. I made some early experiments --- namely a llvm program that printf'd "hello world" -- that seemed to indicate that a bitcode file I generate on linux would work on my solaris box. Well, they're actually the same machine, an amd opteron sun box with a linux vm running. My generating program doesn't run on solaris, but I was hoping to generate bitcode for it from

Hi, I'm currenly working with clang, so I don't have any llvm-gcc installed (I used to have the 4.2 release version, but that broke a lot of tests). A number of tests (test/CFrontend and test/C++Frontend for example) won't run if you don't have llvm-gcc installed, which is good. However, the test/LLVMC tests do run, but fail. These tests test the llvmc2 compiler driver, but they

Hi, I am new to Clang.
