I recently lost a disk on my SparcStation and decided to upgrade all my GNU software as part of rebuilding everything. This may have been a big mistake, since a couple of things that used to work seem to no longer be accepted. Specifically, I am doing MIPS cross tools: gcc 2.8.1 binutils 2.9.1 newlib 1.8.1 with cross-gcc patch, of course. Oh, right, configuration: target=mips-unknown-elf64 --with-gnu-as --with-gnu-ld --with-newlib --prefix=/usr/local/solaris/mips --program-prefix=mips Binutils and gcc build just fine. Even work, mostly. The problems I am seeing have to do with acceptance of options. 1) When building newlib (specifically libgloss), The Makefiles generated by configure include the option -mno_mips16. This seems reasonable to me, but not to the built cross compiler. The build dies as soon as it hits one. I could walk the subtree and edit the Makefiles, but this could take a really long time. 2) The -m4010 switch is accepted by gas, but the 4010-specific instructions are rejected. The old version I still have around (2.6) accepts these just fine. There is a disturbing comment in one of the source files - "Nobody's using the 4010 any more..." I wonder if LSI Logic knows about this? They might have a different opinion. This suggests that the 4010 implementation may have been deliberately broken. 3) ld now complains about mixed ISA levels. That's OK, but it also refuses to link them. I have no problem with a warning, but the MIPS architecture is deliberately backwards compatible, so this should NOT be an error. I think this is a really bad change, and seriously interferes with my work. Does anyone have any good workarounds for these, short of going back to an older version that does what I need? I actually know how to fix the last one, but I'd like to see this get reversed in some future distribution. The others have me perplexed - where in gcc and gas is the code that determines what -m options are accepted? And who decided the 4010 (an embedded core, if you are not familiar with it) was obsolete? Thanks, Ken Kenneth F.
