Bug ID: 83213
Summary: peephole bug with -O2
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Created attachment 42741
gzipped C source code
The attached C code, when compiled by recent gcc trunk and flag -O2,
zend_vm_execute.h:63744:1: error: No region crossing jump at section boundary
in bb 2545
It compiled fine without the -O2 flag.
I'll have a go at finding a range of gcc revisions where
the problem seems to occur and I'll have a go at reducing the code.
I make this the 400th bug I've reported since Oct 2010.
