Re: [libvirt] [PATCH 3/3] build: avoid frame size error when building without -O2

libvirt always adds -Werror-frame-larger-than=4096 to the flags when it builds. When building on Fedora 17, two functions with multiple 1024 buffers declared inside if {} blocks would generate frame size errors; apparently the version of gcc on Fedora 16 will merge these multiple buffers into a single buffer even when optimization is off, but Fedora 17 won't. The fix is to declare a single 1024 buffer at the top of the two offending functions, and reuse the single buffer throughout the functions. --- src/libxl/libxl_driver.c | 5 +---- src/qemu/qemu_driver.c | 10 ++-------- 2 files changed, 3 insertions(+), 12 deletions(-)
