- Subject: Remove non-GAS non-ELF support in alpha backend
While having the osf removal patch reviewed, it turned out that with the
last non-gas non-ELF alpha port gone, there's considerable cleanup
potential in the alpha backend. The following patch implements this:
* HAVE_STAMP_H was only defined by osf5.h, not configure, so the code is
stale.
* All remaining alpha targets use gas, so TARGET_GAS and MASK_GAS can
go. I keep -mgas as a no-op, but completely remove -malpha-as which
can only ever have been used on osf.
* Likewise, all references to ECOFF can be removed, every port that
remains is ELF.
* AFAICS, the remaining ports use DWARF exclusively, so {SDB, DBX,
MIPS}_DEBUGGING_INFO references can be removed.
There are only two issues:
* In alpha.c (alpha_option_override), it's unclear if the optimize > 0
test can be removed completely.
* During testing, I ran into this error:
alpha.md:5861: `*builtin_setjmp_receiver_er_1' matches `*builtin_setjmp_receiver_er_sl_1'
alpha.md:5856: previous definition of `*builtin_setjmp_receiver_er_sl_1'
The condition was the same before I remove the &&
TARGET_AS_CAN_SUBTRACT_LABELS, actually, but to allow the patch to
build, I'm adding && 1 for the moment. No idea what's the proper fix.
Tested with i386-solaris2.11 x alpha-freebsd6.0 and i386-solaris2.11 x
alpha-vms C-only crosses.
Ok for mainline?
