* fold-const.c (fold <MULT_EXPR>): Optimize (C1/X)*C2 into
(C1*C2)/X when unsafe math optimizations are allowed.
(fold <RDIV_EXPR>): Optimize C1/(X*C2) into (C1/C2)/X with unsafe
math optimizations. Minor code clean-ups. Recursively call
fold when constructing sub-expressions.
* gcc.dg/20030826-1.c: New test case.
From-SVN: r70807
* builtins.c (fold_builtin_bitop): New function to perform constant
folding of ffs, clz, ctz, popcount and parity builtin functions
and their long and long long variants (such as ffsl and ffsll).
(fold_builtin): fold_builtin_bitop when appropriate.
* simplify-rtx.c (simplify_unary_operation): Honor both
CLZ_DEFINED_VALUE_AT_ZERO and CTZ_DEFINED_VALUE_AT_ZERO when
evaluating clz and ctz at compile-time, for operands wider
than HOST_WIDE_INT.

gcc:
* config.gcc (hppa*-*-hpux11*, ia64*-*-hpux*): Remove
commented-out logic to use DCE threads (if present), add
support for POSIX threads.
* config/ia64/hpux.h: Define CPP_SPEC to set appropriate
#defines for -pthread. Add -lpthread to LIB_SPEC when
-pthread. In both cases take -mt as a synonym for -pthread
for acc compatibility.
Define GTHREAD_USE_WEAK to 0.
* config/pa/pa-hpux11.h: Likewise for CPP_SPEC and LIB_SPEC.
Remove old logic for DCE threads from LIB_SPEC.
* config/pa/pa64-hpux.h: Define GTHREAD_USE_WEAK to 0.

* config/os/hpux/os_defines.h: Unconditionally define
_GLIBCXX_GTHREAD_USE_WEAK to 0.
From-SVN: r70797
* builtins.c (expand_builtin_mathfn): Rearrange so that we only
return 0 for invalid argument types. Instead drop through to a
call of expand_call at the bottom of function. If op is SQRT,
try attaching a SQRT rtx as the REQ_EQUAL note of the libcall.
