I've been using gcc3.0.2 built for ppc403 (patched to support ppc405; see http://www.kegel.com/xgcc3/ ) for about a year with no trouble, but compiling kaffe exposed an internal compiler error. Since updating to a new compiler is a somewhat major effort, I thought I'd post details about it here, and see if anyone knows what version of gcc (if any) fixes this problem before I start trying versions at random. Here's the compiler error when building kaffe:
../../../kaffe-1.0.7-libtool1.4e/kaffe/kaffevm/support.c:1051: Insn does not satisfy its constraints:
(insn 1003 1000 533 (set (reg/v:DF 40 f8 [77])
(mem:DF (plus:SI (reg/f:SI 31 r31)
(const_int 8 [0x8])) 0)) 293 {*movdf_softfloat32} (nil)
(nil))
../../../kaffe-1.0.7-libtool1.4e/kaffe/kaffevm/support.c:1051: Internal compiler error in reload_cse_simplify_operands, at reload1.c:8364
This probably has to do with the fact that Kaffe is doing floating point stuff, but the ppc405 doesn't have floating point support:
Sigh. I guess I should do a better job with google before I post! I'm still interested in whether there's a good way to make gcc output a more sensible error, if that's all it is. - Dan
