If I install an 8087 math co-processor in my PC, and re-compile the MINIX kernel with the C compiler that comes with MINIX, will it be able to take advantage of the 8087, or does the official MINIX C compiler just ignore 'x87's completely? I also heard references (I think in that file "MINIX INFO" that gets posted every once in a while) to a Pascal compiler for MINIX... Does MINIX come with a Pascal compiler? -- //==========================================================================\\ || Ed Federmeyer || Internet: ed@iitMax.iit.edu || || "Unauthorized access is || Bitnet: sysed@iitVax || || strictly unauthorized." || Office: (312) 567-5981 || \\==========================================================================//

Basically, MINIX ignores the 80x87 chip. The routines save and _restart in kernel/mpx88.s would have to be modified to save/restore the state of the '87 chip if one would attempt to run floating point code. The MINIX C compiler can generate calls to floating point library routines; one might be able to build up support for the '87 chip using the software floating point package posted a few months ago. > I also heard references (I think in that file "MINIX INFO" that gets posted > every once in a while) to a Pascal compiler for MINIX...

No, the Pascal compiler doesn't come with MINIX. > || Ed Federmeyer || Internet: ed@iitMax.iit.edu || -- Guy Helmer ghelmer@dsuvax.uucp Dakota State University Computing Services helmer@sdnet.bitnet USENET: The amateur lawyer forum for the '90s
