Subject: omp-low.c (struct omp_context): Rename combined_into_simd_safelen0 member to combined... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=94e14f2e90e3c13894f3b1df39cd1f28f1081d3b;p=gcc.git

omp-low.c (struct omp_context): Rename combined_into_simd_safelen0 member to combined_into_simd_safelen1.

	* omp-low.c (struct omp_context): Rename combined_into_simd_safelen0
	member to combined_into_simd_safelen1.
	(lower_rec_input_clauses, lower_omp_1): Adjust uses.
	(lower_lastprivate_clauses): Likewise.  For conditional lastprivate
	clauses if ctx->combined_into_simd_safelen1 put statements after the
	predicate conditionalized block rather than into it.
