Hi all,
This converts the preprocessor check for WORD_REGISTER_OPERATIONS into a
runtime check
in reload1.c.
Since this one is used to guard part of a condition, I'd appreciate it
if someone
double-checks that the logic is still equivalent.
Bootstrapped and tested on arm, aarch64, x86_64.
Ok for trunk?
Thanks,

* reload1.c (eliminate_regs_1): Convert preprocessor check
for WORD_REGISTER_OPERATIONS to runtime check.
In this one we had
#if FOO
&& !(condition)
#endif
And you changed it to
&& !(FOO && condition))
Which I think is wrong.
Original:
FOO condition result
0 0 0
0 1 0
1 0 1
1 1 0
New:
FOO condition result
0 0 1
0 1 1
1 0 1
1 1 0
I think you really wanted
&& (FOO
&& ! (condition))
