- Subject: Building gcc for MIPS: mabi=64 and -mips3 instead of -mips4?
Is there any way to build gcc (3.0.4) so that the mabi=64 libraries (MIPS)
are
built for -mips3 instead of -mips4? The system libs (/usr/lib64) are all
mips3.
Second question: Is it important that they match? The linker gives a
warning
if they don't.
What's the minimum processor needed for -mips4? The name seems to imply
R4000, but the gcc man page says r8000 is the default cpu-type. Does this
mean it will issue instructions that can only be run on an r8000 or that it
will
just schedule for an r8000?
