Hello, Ping for one of the changes last proposed here: https://gcc.gnu.org/ml/gcc-patches/2018-11/msg00761.html Submitted separately as an attempt to facilitate the review process. Got access to a linux box, so in addition to the Ada testing we do on cross aarch64-vxworks7, bootstrapped and regression tested on aarch64-linux. This one is just a simple use of REGNUM macros instead of harcoded values in the definition of PROBE_STACK_FIRST_REG and PROBE_STACK_SECOND_REG in aarch64.c. OK to commit ? Thanks in advance! Olivier 2018-12-12 Olivier Hainque * config/aarch64/aarch64.c (PROBE_STACK_FIRST_REG) : Redefine as R9_REGNUM instead of 9. (PROBE_STACK_SECOND_REG): Redefine as R10_REGNUM instead of 10.
