FAQ
I'm failing to install Go 1.1.2 from source on an older Cyrix x86 embedded
system and am hoping someone can point me in the right direction. The
system runs Ubuntu 10.04. The installation fails in
# Building packages and commands for linux/386.
with:
# os/user
SIGILL: illegal instruction
PC=0x80f7b85

go/printer.(*printer).exprList(0x183f9280, 0x10be, 0x1833d880, 0x5, 0x8,
...)
         /usr/local/go/src/pkg/go/printer/nodes.go:206 +0xc75

...)
         /usr/local/go/src/pkg/go/printer/nodes.go:810 +0x15d9

Where would I start looking?
Would trying gccgo make any sense or am I going to hit the same problem
anyway?
Thanks!

    The fucomip instruction was introduced in the Pentium Pro. You are
    using an original version VIA C3, whch is only 486 compatible, not
    even Pentium compatible (thanks for providing the /proc/cpuinfo
    contents). The current 8g compiler assumes that it is always OK to
    generate Pentium Pro instructions. There isn't going to be any simple
    workaround here.

    Drats! But thank you for the help. Do I assume correctly that gccgo should
    work?

    The fucomip instruction was introduced in the Pentium Pro. You are
    using an original version VIA C3, whch is only 486 compatible, not
    even Pentium compatible (thanks for providing the /proc/cpuinfo
    contents). The current 8g compiler assumes that it is always OK to
    generate Pentium Pro instructions. There isn't going to be any simple
    workaround here.

    Yes, gccgo should work.

    this is strange, the GO386 setting should be automatically detected when
    doing native compilation.

    what's the output of $GOROOT/pkg/tool/linux_386/dist env ?
