Bug ID: 62152
Summary: ICE caused by using __builtin_ia32_pause() inside
C++11 noexcept functions on Windows
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: lh_mouse at 126 dot com
// ice.cpp
void foo() noexcept {
__builtin_ia32_pause();
// also reproducable with ::_mm_pause(); (requires #include <immintrins.h>)
}
// EOF
The above code will result in an ICE when compiled to i686 code:
E:\Desktop>g++ ice.cpp -std=c++14 -m32 -c
ice.cpp: In function 'void foo()':
ice.cpp:3:1: internal compiler error: in ix86_compute_frame_layout, at
config/i386/i386.c:9510
}

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://sourceforge.net/projects/mingw-w64> for instructions.
If compiled to x86_64 code it won't ICE on Windows.
