Ian Taylor - Oct. 17, 2012, 5:18 a.m.
There is a function defined in builtins.def as
__builtin_extract_return_addr.  The function is used by that name in
libgcc/unwind-dw2.c.  For some reason the documentation for this
function uses the name __builtin_extract_return_address.  This patch
corrects the documentation to match the definition and usage.
Bootstrapped on x86_64-unknown-linux-gnu.  Committed as obvious.
