Subject: AArch64: Prioritise init_have_lse_atomics constructor [PR 105708]
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=75c4e4909ae2667f56487434f99c2915b4570794;p=platform%2Fupstream%2Fgcc.git

AArch64: Prioritise init_have_lse_atomics constructor [PR 105708]

Increase the priority of the init_have_lse_atomics constructor so it runs
before other constructors. This improves chances that rr works when LSE
atomics are supported.

libgcc/
	PR libgcc/105708
	* config/aarch64/lse-init.c: Increase constructor priority.
