-frecord-gcc-switches is a really cool gcc option to save the CFLAGS a binary was built with in the binary itself. This could help with our bug reporting or with various QA checks. Imagine if `emerge --info cat/pkg` showed the CFLAGS that the binaries were actually built with, instead of some global setting or the CFLAGS environment variable that may well not be respected.
Here's a couple examples of it: comet $ eu-readelf -p /usr/lib/libxdl_view.so | grep -v -e distcc -e ccache String section [25] '.GCC.command.line' contains 1870 bytes at offset 0x69760: [ 27] -march=core2 [ 34] -msse4.1 [ 64] -g [ 67] -O2 [ 6b] -w [ 6e] -ftree-vectorize [ 7f] -frecord-gcc-switches [ 95] -fPIC comet $ eu-readelf -p /bin/ls | grep -v -e distcc -e ccache String section [26] '.GCC.command.line' contains 4558 bytes at offset 0x1b4d0: [ 34] -march=core2 [ 41] -msse4.1 [ 80] -g [ 83] -O2 [ 87] -w [ 8a] -std=gnu99 [ 95] -ftree-vectorize [ a6] -frecord-gcc-switches [ 107e] -I.

Could we do something useful with this? -- Thanks, Donnie Donnie Berkholz Developer, Gentoo Linux Blog: http://dberkholz.wordpress.com
