r216566 (r216568 for 4.9 branch) added %{fno-lto} to LINK_COMMAND_SPEC.
However the linker doesn't understand -fno-lto and errors out.
This causes LTO/PGO bootstrap to fail, because -fno-lto is used during
STAGEprofile.
Fixed by filtering out -fno-lto in collect2.c.

I guess maybe the doloop_end pattern is special? I mean it's a branch insn in a

this is update of my 2013 update to 2012 patch to move rtl loop peeling

No, as I said this is wrong for biarch targets like sparc and
This patch makes GIMPLE forwprop fold all statements, following
single-use SSA edges only (as suggested by Jeff and certainly
how this will regress the least until we replace manual

Our atomic was implemented (by Benjamin IIRC) based on an early
C++0x draft when the spec was still trying to be valid for both C and
C++. Part of the C compatibility aspect was that std::atomic_int is
allowed to be either a typedef for std::atomicint or a base class of
it, so that a C library
Our current C pretty printer output sometimes looks a bit goofy:
expected ‘enum F *’ but argument is of type ‘enum F *’.
It's because it always prints struct/union/enum even though
the type is a typedef name. This patch ought to fix this.
We've got a bunch of reports about this over the years...

Can't you fallback to alloca, or use just alloca, or use alloca
