* include/bits/locale_facets.tcc (num_put::_M_convert_float):
Allow one more digit of precision.
* testsuite/27_io/ostream_inserter_arith.cc: Test that we can
write a double and read back in the same value.

* gensupport.c (first_dir_md_include): Renamed from include;
change all references.
(last_dir_md_include): Renamed from last_include; change all
references.
(init_md_reader): Unconditionally initialize base_dir whether or
not filename is a relative path.
From-SVN: r50465
Fix for PR java/5812.
* expr.c (build_java_jsr): Take pc arguments, and do lookup_label
gere instead of in JSR macro. Likewise with load_type_state call.
Do the latter on if the return_pc has been verified (the jsr returns).
(JSR): No just call build_java_jsr.

* cfgrtl.c (purge_dead_edges): Set BB_DRITY flags if edge has been
removed; fix return value.
* combine.c (combine_instructions): Dirtify blocks where we failed to
update liveness; purge dead edges; use update_life_info_in_dirty_blocks.
* toplev.c (rest_of_compilation): Do not purge_dead_edges after combine.

* include/std/std_limits.h: Move static const data members out of
generic template, into base class __numeric_limits_base.
* src/limits.cc: Add definitions.
* config/linker-map.gnu: Add __numeric_limits_base.
* testsuite/18_support/numeric_limits.cc: Declare test in scope.
From-SVN: r50447
* config/gofast.h (GOFAST_RENAME_LIBCALLS): Set gt and ge as
NULL_RTX. Set all HFmode operations as NULL_RTX.
* optabs.c (prepare_float_lib_cmp) <GT, GE, LT, LE>: If libfunc is
NULL_RTX, try reversing the comparison and the operands.

* defaults.h (MODE_HAS_NANS, MODE_HAS_INFINITIES): New.
(MODE_HAS_SIGNED_ZEROS, MODE_HAS_SIGN_DEPENDENT_ROUNDING): New.
* flags.h (HONOR_NANS, HONOR_INFINITIES, HONOR_SIGNED_ZEROS): New.
(HONOR_SIGN_DEPENDENT_ROUNDING): New.
* builtins.c (expand_builtin_mathfn): Use HONOR_NANS.
* c-common.c (truthvalue_conversion): Reduce x - y != 0 to x != y
unless x and y could be infinite.
(expand_unordered_cmp): New, mostly split from expand_tree_builtin.
Check that the common type of both arguments is a real, even for
targets without unordered comparisons. Allow an integer argument
to be compared against a real.
(expand_tree_builtin): Use expand_unordered_cmp.
* combine.c (combine_simplify_rtx): Use the new HONOR_... macros.
* cse.c (fold_rtx): Likewise. Fix indentation.
* fold-const.c (fold_real_zero_addition_p): New.
(fold): Use it, and the new HONOR_... macros.
* ifcvt.c (noce_try_minmax): Use the new HONOR_... macros.
* jump.c (reversed_comparison_code_parts): After searching for
the true comparison mode, use HONOR_NANS to decide whether it
can be safely reversed.
(reverse_condition_maybe_unordered): Remove IEEE check.
* simplify-rtx.c (simplify_binary_operation): Use the new macros
to decide which simplifications are valid. Allow the following
simplifications for IEEE: (-a + b) to (b - a), (a + -b) to (a - b),
and (a - -b) to (a + b).
(simplify_relational_operation): Use HONOR_NANS.
* doc/tm.texi: Document the MODE_HAS_... macros.
