Jean-Marc, Are you sure that you don't need to add just -msse to enable the intrinsics rather than a full fledged -march=pentium3? I did some playing around and I can get intrinsics code to compile with -march=i686 -msse on linux with that. Check out: http://groups.google.com/groups?q=enable+gcc+sse+intrinsics&hl=en&lr=&ie=UTF-8&amp...

When compiling Speex 1.1.4 with GCC 3.3.2, the option -msse must be added to the CFLAGS in libspeex/Makefile. GCC 3.1.1 added a new option "-msse" (see http://gcc.gnu.org/gcc-3.1/changes.html , specifically under "New Targets and Target Specific Improvements") to enable SSE instructions within the compiler's output (for appropri...

It's easy enough to test whether gcc will accept -msse and ifdef out the intrinsics code otherwise. I suppose you could also just try compiling a sample of the intrinsics in case, but gcc and MSVC are the only two targets you're likely to need to support in the near future. -r --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg pr...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Indeed, the reason that -msse* are there is because it's needed for actually compiling the tests (because of the #include of the intrinsics). But of course, -msse* has the side effect of (sometimes) producing illegal instructions. We'll definitely need to fix this, but I don't know how yet. In the mean time, you can...

Hi Andrew- > fatal error: error in backend: SSE2 register return with SSE2 disabled Is this for 32-bit or 64-bit x86? If it's the latter, the ABI demands that the return value in this case is in xmm0 - SSE is required. Alistair

Hi Andrew- > Well -no-sse -mno-mmx works for EFI as it is pre-boot firmware and does not have any floating point C code. We use -no-sse and -mno-mmx code to prevent optimized code gen using these registers for optimizations. Whether it's optimised or not doesn't particularly matter, the x86_64 ABI says that floating-point return values go into SSE registers, so that is where LLVM is

I know you're a skilled programmer, but... maybe you forgot to add -msse compiler option? -msse for SSE code, -msse2 for SSE2 code, -msse4.1 for SSE4.1 code

It only tries if the use passes --enable-sse; testing by target arch as Aron suggested is another reasonable approach. However, the -msse cflag test fails on p...

...hed patch changes the configure.ac logic as follows: It tests if the current compiler/cflags combination supports SSE, and if so enables _USE_SSE. This can be overridden by the '--enable-sse' and '--disable-sse' flags. Using '--enable-sse' will additionally add '-O3 -msse' to CFLAGS, just as it used to. I've tested this using the following combinations: x86_64: ./configure: Detected and used. x86_64: ./configure --disable-sse: Detected but not used. i686: ./configure: Not detected. i686: CFLAGS="-march=pentium3" ./configure: Detected and used. i68...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Jesus, Thanks for the report. As far as I can tell, what's happening is that when intrinsics are enabled, we compile all tests with -msse4.1, even when it's only run-time detected. In most cases, that doesn't cause any issue, but sometimes the compiler will take the C code and generate an SSEx instruction on its own. I think this is what's happening for you. The actual encoder and decoder should work fine since they are c...

If, however, you need Speex 1.1.4, the easiest fix is to configure with: CFLAGS='-msse' ./configure --enable-sse [other options] or CFLAGS='-g -O2 -msse' ./configure --enable-sse [other options] (just be certain to specify appropriate flags). A "cleaner" solution is to edit libspeex/Makefile after running configure, and add "-msse" (without quotes)...
