From 3426ae5760319b6b31d71f3ba798154e6fcea34d Mon Sep 17 00:00:00 2001 From: Alan Hayward Date: Wed, 26 Jun 2019 14:10:08 +0100 Subject: [PATCH] Arm: Allow version strings in the triplet regexp On Arm, the OS may use the full version string for the arch name when installing the compiler, for example armv7hl-redhat-linux-gnueabi-gcc. Implement gdbarch_gnu_triplet_regexp for Arm to allow this to be detected. Ensure that other Arm targets (eg iwmmxt) are not affected. This fixes the compile/ set of tests on those systems. gdb/ChangeLog: 2019-06-26 Alan Hayward * arm-tdep.c (arm_gnu_triplet_regexp): New function.
