The new code ought to go before the HARD_REGISTER_P check, not after it.

Hi,
The attached patch adds some more test cases for PR 50751.
Tested on sh-sim with
make check-gcc RUNTESTFLAGS="sh.exp=pr50751* --target_board=sh-sim
\{-m2/-ml,-m2/-mb,-m2a-single/-mb,-m4-single/-ml,
-m4-single/-mb,-m4a-single/-ml,-m4a-single/-mb}"
to confirm that the tests pass as expected.

This patch simplifies TRY_EMPTY_VM_SPACE for Linux hosts by checking
pointer size when appropriate. Tested on Linux/x86-64, Linux/ia32

Hello,
The attached patch make the code use some more 'bool' and 'NULL_RTX'.
Tested with 'make all-gcc'.
OK?
ChangeLog:

* config/sh/sh.c (INSN_REGMODE_WEIGHT, CURR_REGMODE_PRESSURE):
Fix line width.

The default expansion of bswapsi2 (and bswapdi2) is pretty suboptimal.
Tested on m68k-linux.
