From 9a60d8a43047981640318990aebe31b1d99107fe Mon Sep 17 00:00:00 2001 From: Weiyi Wang Date: Sat, 5 Oct 2019 10:45:01 -0400 Subject: [PATCH] unfold UNREACHABLE implementation for dumb compilers We relies on UNREACHABLE's noreturn attribute to eliminate parent's "no return value" warning. However, this was wrapped in a `if(!false)` block, which compilers may not unfold to recognize the noreturn nature. --- src/common/assert.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/common/assert.h b/src/common/assert.h index 4b0e3f64ee..3b4d92b30d 100644 --- a/src/common/assert.h +++ b/src/common/assert.h @@ -41,8 +41,8 @@ __declspec(noinline, noreturn) } \ while (0) -#define UNREACHABLE() ASSERT_MSG(false, "Unreachable code!") -#define UNREACHABLE_MSG(...)
