...of -ffast-math). As mentioned earlier, a number of other compilers also generate NaN with -ffast-math or its equivalent. I believe this is done to comply with the Posix wording. Regardless of feelings about playing benchmark games (with which I have sympathy), people tend to compile many of the SPECfp benchmarks with -ffast-math so they can, e.g., use FMA instructions in their publishes. But this is a side issue, and I'm rather sorry I mentioned SPEC at all. This is really an issue of internal and external consistency. Thanks, Bill > > – Steve

Hi, I've trying to test a pass with a C version of the 171.swim SPECfp benchmark. If I run llvm-gcc on the C files, I can generate a functioning executable. However, if I use llvm-gcc with -emit-llvm, then run lli on the resulting bitcode, I get the following error: lli: /x/jeffhao/llvm/llvm-2.4/lib/ExecutionEngine/JIT/JIT.cpp:467: void llvm::JIT::runJITOnFunction(...

My guess would be that people don't tend to run with -ffast-math (it's got a reputation for breaking code, even ignoring this particular issue). Without that, from what I can see the issue

...Additionally, I don't think the programs get executed at all, because make runs too fast. For gap/gcc, only the cbe test fails, the other (including JIT) are ok.

I've got a couple of SPARCstation 2s (about as fast as a fast 486, for most thing) that I'm going to be using for some testing. I realize that these machines are a bit slow, but when connecting via OpenSSH, it's MUCH slower than connecting to my 486-DX 50. The point where it waits is just after "debug: Sent encrypted session key.". The pause is for about 10 seconds, while

...pport for the other GCC front-ends is not very difficult. It basically amounts to implementing the langhooks that are used to expand the language-specific tree nodes into the appropriate LLVM code. Of all of them, having G77 would be particularly nice, because it would allow us to run the rest of SpecFP, though f2c might be another option if it works very well (I've never tried it before). Long-term we'd like to have a nice F90 front-end, perhaps based on the Cray front-end. If anyone is interested in Fortran, this would be an excellent project. :) > 3.

Hey guys, I've recently implemented gluster to share webcontent read-write between two servers. Version : glusterfs 3.0.4 built on Apr 19 2010 16:37:50 Fuse : 2.7.2-1ubuntu2.1 Platform : ubuntu 8.04LTS I used the following command to generate my configs: /usr/local/bin/glusterfs-volgen --name repstore1 --raid 1 10.10.130.11:/data/export
