acconfig.h (HAVE_GAS_MAX_SKIP_P2ALIGN): New tag.
* acconfig.h (HAVE_GAS_MAX_SKIP_P2ALIGN): New tag.
* configure.in: Check for it.
* i386/gas.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Use it.
* final.c (uid_align, uid_shuid, label_align): Make static.
(label_align): Change type to struct label_alignment pointer.
(LABEL_TO_ALIGNMENT, shorten_branches): Update due to type change.
(LABEL_TO_MAX_SKIP): Define.
(LABEL_ALIGN_MAX_SKIP, LOOP_ALIGN_MAX_SKIP,
LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Provide defaults.
(shorten_branches): Record the maximum bytes to skip when
aligning a label.
(final_scan_insn): Use the maximum bytes to skip when aligning a label
if ASM_OUTPUT_MAX_SKIP_ALIGN is available.
* i386.h (LOOP_ALIGN_MAX_SKIP,
LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Define.
* i386.c (override_options): i386_align_jumps and i386_align_loops
default to 4 if ASM_OUTPUT_MAX_SKIP_ALIGN is available.
* invoke.texi: Document new i386 align-loops and align-jumps behavior.
