From 9693501c158d68431962938cb02e7d8d2ef89ca3 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 24 Jul 2013 02:17:02 -0400 Subject: change jmp_buf to share an underlying type and struct tag with sigjmp_buf this is necessary to meet the C++ ABI target. alternatives were considered to avoid the size increase for non-sig jmp_buf objects, but they seemed to have worse properties. moreover, the relative size increase is only extreme on x86[_64]; one way of interpreting this is that, if the size increase from this patch makes jmp_buf use too much memory, then the program was already using too much memory when built for non-x86 archs. --- src/signal/siglongjmp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/signal/siglongjmp.c') diff --git a/src/signal/siglongjmp.c b/src/signal/siglongjmp.c index a7bcca24..2974ff7f 100644 --- a/src/signal/siglongjmp.c +++ b/src/signal/siglongjmp.c @@ -7,5 +7,5 @@ _Noreturn void siglongjmp(sigjmp_buf buf, int ret) { if (buf->__fl) __restore_sigs(buf->__ss); - longjmp(buf->__jb, ret); + longjmp(buf, ret); } -- cgit v1.2.1
