Hello all, I have something for the daring folks among you: a GPC, based on the latest Cygnus CDK snapshot. For those of you who don't know, the Cygnus snapshots are GCC development releases, so you could consider this to be a pre-2.8 GCC. I used GPC-alpha 970510. I tested it on linux and SGI irix and had no problems with it (yet). Now, GPC alpha releases are usually quite reliable, but this is a major change in code, so you could consider this _REALLY ALPHA_ ;-) It can do some cool things like pentium(pro) optimizations. I would love to hear from somebody who does lots of floating point on a pentium(pro) whether it's really is faster. Binaries for pentiumpro-intel-linux (RedHat 4.1) and mips-sgi-irix6.2 are available. The mips binary is not targeting 64bits because of the immaturity of mips64 support in GCC. The linux binary installs in /opt/cdkgpc-i970518. You can move it around, just make sure you don't install it over your existing GCC. URL: ftp://agnes.dida.physik.uni-essen.de/home/janjaap/cygnus-970507 Apart from numerous "easy fixes" and manual patching, these changes were necessary because of changes in GCC internals: gpc-decl.c: build_complex(): extra argument. setop.c: clear_storage(): New last argument. Probably clear blocksize. set to 1. Not most efficient, but works. gpc-cccp.c: quick hacks to add: int c89 UCHAR is_space Known bugs: (1) "automake" is completely broken. Still looking for a fancy solution that enables us to share the `gcc' driver with GCC. (2) Some files not modified but reused from 2.7.2.x: gpc-cccp.c, gpc-lex.c Todo: All cygwin32 related patches were removed from GPC and must be put back in. Must check for cygwin32-beta18 compatibility. *maybe* do a djgpp version. BTW: I don't plan to maintain a seperate Cygnus CDK GPC source tree. You could consider this a techdemo: the effort and results will pay off once GCC 2.8 is released, because porting GPC will be much easier then. Happy hacking!
