Adding target -march=dlx (for DLX) to GCC-3.4.x?
I'm using extensively DLX in the development of several simple DLX programs in Verilog, VHDL, C, Pascal, Oberon-2, ... and in the construction of different easy compilers targeting DLX. I need an updated GCC compiler for DLX, preferibly GCC-3.4.x because it's more easy, stable and less complex than GCC-4.x. Best regards, Anny Blackyew
i386.md from GCC-4.1.1-RC1 and GCC-4.2-ss has bugs!
i386.md from GCC-4.1.1-RC1 and GCC-4.2-ss has bugs! i386.md from GCC-4.1.1-RC1 has the sharp symbol '#': "f#x,x#f", "f#x,xm#f", "f#rx,..#fx,..#rf", ... i386.md from GCC-4.2-ss has corrected it and has not the sharp symbol '#': "f,x", "f,xm", ... What is the meaning of repeated words in i386.md? like: * ssemov,ssemov (in 4.1) vs sselogl,ssemov (in 4.2). * fmov,fmov,fmov,imov,imov (both) Anny
Missing -march=sempron -mtune=sempron -msse3 -m3dnow+?
Why is GCC-4.2.x missing -march=sempron -mtune=sempron -msse3 -m3dnow+? Why is GCC-4.2.x missing -march=k8 -mtune=athlonxp -mtune=athlon-xp -mtune=athlon_xp -msse3 -m3dnow+ -m32? Why is the table gcc/config/i386/i386.c:processor_alias_table[] small and unextendable? GCC want to say me bad news for powerful antiquities "Athlon-XP TBred", "Athlon-XP Barton", "Athlon64 Venice (939 pins and SSE3)" since 4 years and their performance match to the current processors.

The big problem is that none of these work! It's due to many ocurrences of
athlon_* and athlon-* in the bash and m4 scripts (overall in "case") and
{.c,.h}.
athlon | athlon_*) in a location
athlon | athlon-*) in another location (but why?)
Other problem is the ambiguity of "athlon-xp-pc-linux-gnu" that
could not match with the regular expression *-*-linux-*.
It's contrary to the unambiguity of "i686-pc-linux-gnu", 3 minus signs
versus 4 minus signs.
