I think that is the last patch required for commonly used code.
Remaining are issues with array constructors and concatenations - and,

The routine uses an anonymous static variable and this breaks in LTO mode
because a DECL_NAME is expected.
Tested on i586-suse-linux, applied on the mainline and 4.7 branch.

The only change is to make the result of the functions an int

The problem here is that when libgcc goes to try to figure out the
size of double/long double, it includes some headers. But those
headers does not exist when doing a stage1 Linux cross compiler
build.
This fixes the problem having configure not include those headers.

The label is for branching *around* a block calling a noreturn

emit_cmp_and_jump_insns with EQ. All ports defining it seem ok.
They'd notice very quickly, no code compiled with

Currently, powerpc-linux gcc -Os -mno-multiple uses out-of-linux gpr

slower than an inline save/restore. The only case where it might win
