--- Merging (from foreign repository) r68152 into '.':
U gcc/llvm-convert.cpp

U gcc/llvm-debug.h
Fix nondeterminism in whether line numbers got
generated near the beginning of a function. Now
they do, an improvement. This allows checking
in 67884 finally:
Enable debug info at -O. I've fixed a lot of
bugs where -g affects optimization recently; there
are currently no such cases in the llvm testsuite or
a substantial amount of other code on Darwin, which
seems sufficient to turn it on. Woot. I make
no claims about the quality of the generated debug
info.
Any cases where you see -g affecting optimization can
now usefully be reported as bugs. TEST=ipodbgopt should
test this in the llvm testsuite.
