- Subject: [PATCH] Simplify tic6x and s390x expedite registers
- Authentication-results: sourceware.org; auth=none
Nowadays, we have six tic6x expedite registers, which are duplicated.
tic6x-c64xp-expedite = A15,PC
tic6x-c64x-expedite = A15,PC
tic6x-c62x-expedite = A15,PC
tic6x-c64xp-linux-expedite = A15,PC
tic6x-c64x-linux-expedite = A15,PC
tic6x-c62x-linux-expedite = A15,PC
in features/Makefile, we have
echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
>> $(outdir)/$*.tmp
which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite. We can define only one generic
expedite register for all different ti6cx and s390x target descriptions.
Actually, we've done that for x86 target descriptions.
Re-run 'make GDB=/path/build/gdb all' to regenerate regformats/*.dat files,
and they are not changed. I'll push it in.
