| commit gcc-14-5284-g3f176e1adc6
| Author: Tamar Christina <tamar.christina@arm.com>
| Date: Thu Nov 9 13:59:39 2023 +0000
|
| middle-end: optimize fneg (fabs (x)) to copysign (x, -1) [PR109154]
|
| This patch transforms fneg (fabs (x)) into copysign (x, -1) which is more
| canonical and allows a target to expand this sequence efficiently. Such
| sequences are common in scientific code working with gradients.
|
| There is an existing canonicalization of copysign (x, -1) to fneg (fabs (x))
| ... 25 lines of the commit log omitted.
