From bb675539ba2f661c6bfab258847b41798a449432 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Sat, 3 Oct 2020 13:51:29 +0100 Subject: [PATCH] Darwin : Only emit Objective-C section switches for older linkers. At one time, the system linkers needed to have at least a dummy entry for every Objective-C section in use. This removes the extra emitted code when it is not needed by the linker. gcc/ChangeLog: * config/darwin.c (output_objc_section_asm_op): Avoid extra objective-c section switches unless the linker needs them. --- gcc/config/darwin.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/gcc/config/darwin.c b/gcc/config/darwin.c index e101f8eb655..370ee5cedaa 100644 --- a/gcc/config/darwin.c +++ b/gcc/config/darwin.c @@ -136,7 +136,7 @@ output_objc_section_asm_op (const void *directive) order in the object.
