From 8234b0dcb2484f836d0fb8f12aa6b04f5e66db6f Mon Sep 17 00:00:00 2001 From: Eric Botcazou Date: Mon, 10 Jan 2022 12:40:10 +0100 Subject: [PATCH] Properly enable -freorder-blocks-and-partition on 64-bit Windows The PR uncovered that -freorder-blocks-and-partition was working by accident on 64-bit Windows, i.e. the middle-end was supposed to disable it with SEH. After the change installed on mainline, the middle-end properly disables it, which is too bad since a significant amount of work went into it for SEH. gcc/ PR target/103465 * coretypes.h (unwind_info_type): Swap UI_SEH and UI_TARGET. --- gcc/coretypes.h | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/gcc/coretypes.h b/gcc/coretypes.h index 0769a78a87c..f3559373433 100644 --- a/gcc/coretypes.h +++ b/gcc/coretypes.h @@ -228,15 +228,17 @@ enum stack_protector { SPCT_FLAG_EXPLICIT = 4 }; -/* Types of unwind/exception handling info that can be generated. */ +/* Types of unwind/exception handling info that can be generated. + Note that a UI_TARGET (or larger) setting is considered to be + incompatible with -freorder-blocks-and-partition. */ enum unwind_info_type { UI_NONE, UI_SJLJ, UI_DWARF2, - UI_TARGET, - UI_SEH + UI_SEH, + UI_TARGET }; /* Callgraph node profile representation. */ -- 2.34.1
