Subject: [PATCH] Enable LRA for ia64
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This was tested by bootstrapping GCC natively on ia64-t2-linux-gnu and
running the testsuite (based on
236116068151bbc72aaaf53d0f223fe06f7e3bac):
https://gcc.gnu.org/pipermail/gcc-testresults/2024-June/817268.html
For comparison, the same with just
236116068151bbc72aaaf53d0f223fe06f7e3bac:
https://gcc.gnu.org/pipermail/gcc-testresults/2024-June/817267.html

* config/ia64/ia64.cc: Enable LRA for ia64.
* config/ia64/ia64.md: Likewise.
* config/ia64/predicates.md: Likewise.
