search for: __llvm__

Hi all In unittests/ADT/APIntTest.cpp I came across this test: // XFAIL this test on FreeBSD where the system gcc-4.2.1 seems to miscompile it. #if defined(__llvm__) || !defined(__FreeBSD__) TEST(APIntTest, i33_Count) { APInt i33minus2(33, static_cast<uint64_t>(-2), true); EXPECT_EQ(0u, i33minus2.countLeadingZeros()); EXPECT_EQ(32u, i33minus2.countLeadingOnes()); EXPECT_EQ(33u, i33minus2.getActiveBits()); EXPECT_EQ(1u, i33minus2.countTrailingZ...

It was added in the same commit, and given the comment above I think it's probably so the test still runs on FreeBSD if Clang is self-hosting. Tim.

...e any major problems. A couple of things I noticed when configuring newlib for LLVM. First, I did not find any preprocessor symbols that I could use to identify that we are compiling to LLVM byte code. If there is one, I'd be happy to hear it, but if not, then it might be a good idea to define __LLVM__ or something like that in (by) llvm-gcc. Another related thing is that even when I defined -emit-llvm in what I thought would be a global CFLAGS for all of newlib, it did not get propagated to all subdirectories. I solved both of these issues by creating a shell script that is just a fall-throug...

Hi Kent, I suggest you open a bug report with a preprocessed testcase.

Try: <path-to-llvm-gcc-install>/llvm-cpp -dM /dev/null | grep -y llvm llvm-cpp should be installed if you built the gcc frontend. Mine reports __llvm__.

I've had good luck using the llvm-gcc & llvm-g++ on small projects, but I just discovered that it's apparently missing some of the GCC intrinsic functions -- specifically, when I try and compile VXL (http://vxl.sourceforge.net) it dies when it encounters __builtin_bswap32 . This is on OS X with the llvm-gcc-4.2 & llvm_g++-42 that are part of the XCode 3.2.3 I don't know if

Hi: I've been able to compile the attached "helloworld.c" file converted from "helloworld.cpp". My question is how does one usually use __main() and CODE_FOR_MAIN() in tying up with the rest of the code? Attached here are the original "helloworld.cpp" and "helloworld.c" files. Thanks.

When I compiled a linux kernel, gccas was used to compile assembly code. But gccas cannot recognize the line comment character "#" of gnu assembler, and abort the compile with reporting a error "syntax error, unexpected $undefined". I watch llvm/tools/gccas, but donot known how to add this function in it. Would you give me some suggestions? Thanks.
