Original patch from: ../4.3.2/110-trampolinewarn.patch

Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch
|
|
This trivial patch causes gcc to emit a warning whenever
|
|
it generates a trampoline. These are otherwise hard to
|
|
locate. It is rigged to default ON - to have it default
|
|
to OFF remove the text 'Init(1)' from the common.opt
|
|
patch, leaving just 'Common Var(warn_trampolines)'.
