Make it possible to build old kernels with gcc4 for armv7 and aarch64. The packages have been generated with (as usually): $ pmbootstrap aportgen gcc4-aarch64 gcc4-armv7 [ci:skip-build]: I have tested that this builds locally. Fixes #193.

Subject: [PATCH] Pass unpromoted argument to promote_function_mode
|
|
|
|
This patch updates setup_incoming_promotions in combine.c to match what
|
|
is actually passed in assign_parm_setup_reg in function.c.
|
|
|
|
Backported from mainline:
|
|
|
|
gcc/
|
|
|
|
PR rtl-optimization/64037
|
|
* combine.c (setup_incoming_promotions): Pass the argument
|
|
before any promotions happen to promote_function_mode.
|
|
|
|
gcc/testsuite/
|
|
|
|
PR rtl-optimization/64037
|
|
* g++.dg/pr64037.C: New test.
