From ece5067ec1fc8a653b9c6585ef545524608ce0a3 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Wed, 2 Sep 2020 20:33:00 +0100 Subject: [PATCH] Darwin, Arm64 : Make trampoline templates linker-visible. Actually, the LTRAMPn symbols _are_ 8 byte aligned, but because they are Local, the linker doesn't know that this guarantee can be met. It assumes that they are not necessarily more aligned than the containing section (ld64 atoms strike again). The fix is to publish the trampoline symbol for the linker to access directly - it can then see that the atom is suitably aligned. Fixes issue #11. --- gcc/config/darwin.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/gcc/config/darwin.h b/gcc/config/darwin.h index 1b26e6d0bea2..63c2e30dfa73 100644 --- a/gcc/config/darwin.h +++ b/gcc/config/darwin.h @@ -826,6 +826,8 @@ extern GTY(()) section * darwin_sections[NUM_DARWIN_SECTIONS]; sprintf (LABEL, "*%s%ld", "lubsan_type", (long)(NUM));\ else if (strcmp ("LASAN", PREFIX) == 0) \ sprintf (LABEL, "*%s%ld", "lASAN", (long)(NUM));\ + else if (strcmp ("LTRAMP", PREFIX) == 0) \ + sprintf (LABEL, "*%s%ld", "lTRAMP", (long)(NUM));\ else \ sprintf (LABEL, "*%s%ld", PREFIX, (long)(NUM)); \ } while (0)
