* pa.c (apparent_fsize): Delete variable.
(compute_frame_size): Many changes. Return the total frame size,
including space for "magic" stuff at the top of the stack and any
rounding for the Snake.
(output_function_prologue): Don't take a leaf_function argument;
Decide that based on frame size and frame_pointer_needed.
Don't emit any frame diddling code if actual_fsize is 0.
(output_function_epilogue): Don't take leaf_function argument.
Don't do anything if no frame.
Keep stack pointer aligned to 64 bytes before loading from old
frame pointer.
(hppa_epilogue_delay_slots): Only if there is no frame will we
have an empty delay slot to fill.
(eligible_for_epilogue_delay): Don't check "leaf_function" anymore.

* pa.h (CONST_COSTS): Make CONST_DOUBLES very expensive.
Give HIGH expressions a small cost with CONST, SYMBOL_REF,
and LABEL_REF being twice as expensive as HIGH.
From-SVN: r3071
* pa.c (fmpyaddoperands): Verifys given registers are suitable for
use in fmpyadd instructions.
(fmpysuboperands): Likewise, but for fmpysub instructions.
From-SVN: r3070
* pa.md (fmpyadd peepholes): New peepholes to issue independent
floating point multiply and add instructions at the same time.
(fmpysub peepholes): Likewise for multiply and subtract instructions.
From-SVN: r3069
(collect2.o): Don't need STANDARD_STARTFILE_PREFIX, etc.
(install-cross-tools): Use REAL_LD_NAME instead of `ld' when linking
files from tooldir to libsubdir.
From-SVN: r3053
Fix typo in -debug part of previous change.
Look for tools using paths rather than a single prefix.
(struct prefix_list, struct path_prefix): New structures.
(cpath, path): New variables.
(find_a_file, add_prefix): New functions; simplified versions of
functions from gcc.c.
(prefix_from_env): New function.
(main): Get path to search for binaries from COMPILER_PATH
environment variable always set by gcc.c and from PATH.
Qualify names with target machine in cross-environment unless
using compiler directories.
Use find_a_file to find our binaries.
Remove use of single prefix.
If -debug, print strip_file_name.
(fork_execute): Print program we are trying to execute if -debug and
we can't find the file.
(scan_prog_file): Complain if can't find nm.
From-SVN: r3052
* pa.md (movqi, movhi, movsi, movdi, movsf, movdf): Fix attributes
which involve fp<->gr copies to match current reality.
(indexed loads): These should have "load" attributes, not "move".
From-SVN: r3043
make multiple register operands equivalent if the last register of
the groups are the same.
(subst_reloads): Use gen_lowpart_common to change mode of
reloadreg.
From-SVN: r3030
TARGET_SWITCHES): Delete support for non-existent CPU variations.
(ASM_SPEC, LINK_SPEC, TARGET_SWITCHES): Add support for -mlink-relax.
(SELECT_CC_MODE): Correct typo.
