A first implementation of the algorithm was already in 3_4, under the name
expand_cmplxdiv_wide (in optabs.cc), then Rth rewrote it in the tree-ssa branch
as part of the new tree-complex.cc (It would be mildly interesting to see if
the version in 3_4 works) In the meanwhile, I'm adding Rth in CC of 19486.
Indeed (ChangeLog.1):
Tue May 18 03:53:37 1999 Craig Burley <[EMAIL PROTECTED]>
Improve open-coding of complex divide:
* flags.h: Declare new front-end-malleable flag.
* toplev.c: Define new flag.
* optabs.c (expand_cmplxdiv_straight): New function to do original
open-coding.
(expand_cmplxdiv_wide): New function to do new open-coding,
from Toon Moene, with changes (call to emit_barrier, dropping
of spurious `ok = 1;', plus the obvious `break;' -> `return 0;').
(expand_binop): A bit of spacing fixing, while at it.
Use new functions instead of inlining the open-coding code.
