* semantics.c (simplify_aggr_init_exprs): New function.
(expand_body): Use it.
* tree.c (walk_tree): Special-case TARGET_EXPRs since they
sometimes present the same sub-tree twice.
From-SVN: r30849

MULTILIB_OPTIONS.
From-SVN: r30841

Also don't clobber %g2 register in 32bit SPARC assembly, so that
-mno-app-regs libgcc can be compiled.
* libgcc2.c: Add defines so that the updated longlong.h
can be used in libgcc2.a. Also, make sure on most architectures
(at least on all which have optimized code in longlong.h defined
for) {SI,W}_TYPE_SIZE is suitable for preprocessor tests.
From-SVN: r30836

FPBIT.
From-SVN: r30828

* config/sparc/linux64.h: Default to -mcpu=ultrasparc if no
-mcpu is given and we're doing 64bit compiles.
From-SVN: r30825
* config/sparc/sparc.c (hard_32bit_mode_classes): Mark registers
suitable for holding OFmode values so that gcc works with complex
quad long doubles.
(hard_64bit_mode_classes): Likewise.
From-SVN: r30821

chain if non existant (don't rely on the verified state of the jsr
target.)
Tue Nov 23 17:29:40 1999 Alexandre Petit-Bianco <apbianco@cygnus.com>
* verify.c (merge_type_state): Non verified subroutines being
considered more than once to trigger passive type merge.
From-SVN: r30811
* combine.c (check_promoted_subreg, record_promoted_value): New
functions.
(combine_instructions): Use them to retain nonzero and sign bit
information after SUBREGs are eliminated by optimizations in
this pass if PROMOTE_FUNCTION_RETURN.
