* emit_rtl.c (init_emit_once): Ensure that potential aliasing
between frame_pointer_rtx, hard_frame_pointer_rtx, and
arg_pointer_rtx is respected in initialization.
(init_emit_once): Use gen_rtx_raw_REG() to create
return_address_pointer_rtx.
* rtl.h: Fix typo.
From-SVN: r17409
* combine.c (force_to_mode, nonzero_bits): Correctly optimize
constant offset computations from objects with known alignment in
the presence of STACK_BIAS.
From-SVN: r17405
* acconifg.h (NEED_DECLARATION_ATOL): New declaration to check for.
* rtl.c (atol): Only provide the declaration if NEED_DECLARATION_ATOL.
From-SVN: r17404
* varasm.c (immed_double_const): Add casts to HOST_WIDE_INT where
necessary.
(const_hash): Hash val is unsigned long.
(SYMHASH): Likewise.
* tree.c (TYPE_HASH): Type of hash val is unsigned long.
* print-tree.c (print_node_brief): HOST_PTR_PRINTF format wants a
char pointer, not HOST_WIDE_INT.
(print_node): Likewise. Also hash is unsigned long not
HOST_WIDE_INT.
* cse.c (canon_hash): Hash is unsigned long not HOST_WIDE_INT.
From-SVN: r17403
* explow.c (optimize_save_area_alloca): New function for targets
where SETJMP_VIA_SAVE_AREA is true.
(allocate_dynamic_stack_space): On SETJMP_VIA_SAVE_AREA targets,
compute the amount of stack space needed should we find later that
setjmp is never called by this function, stuff rtl for this inside
a REG_NOTE of the final SET of stack_pointer_rtx.
* toplev.c (rest_of_compilation): If SETJMP_VIA_SAVE_AREA and
current_function_calls_alloca, call optimize_save_area_alloca.

* loop.c (find_and_verify_loops): When attempting to move insns from
inside the loop outside the loop, create a BARRIER if no suitable
one was found.
From-SVN: r17399
* configure.in (NON_UNIX_STDIO): Define if MINGW32.
(NON_ANSI_RW_MODE): Do not define for CYGWIN32 or MINGW32.
* libI77/rawio.h: Don't providing conflicting declarations for
read() and write(). MINGW32 header files use "const" quals.
* libF77/s_paus.c: _WIN32 does not have pause().
From-SVN: r17397
* pexecute.c (pexecute): New function for mingw32. Supports pipes.
(pwait): New function for mingw32.
* gcc.c (execute): Mingw32 pexecute() supports pipes, but cygwin32
pipe support is broken for now.
