I'm doing some research on a pretty plain 32-bit RISC architecture that has
some extra facilities for doing vector operations. Not exactly new, I know.
The difference with this one is that the vectors are pairs of normal
registers.
This isn't all that new; lots of architectures have normal regi

We could change CSA so that when it combines a prologue instruction
with a non-prologue instruction it sets a new flag on the instruction,
and uses a table on the side to record the original values in the
instruction.
I guess that would w

Mike Stump already filed a PR about this, PR 28778 and I gave a full testcase
which shows that this is legal code and the compiler should not be removing
the store.
Oh and I marked it as a

Here's my reduced testcase:
typedef long GLint;
extern void aglChoosePixelFormat(const GLint *);
void find(const int *alistp) {
const int *blist;
int list[32];
if (alistp)
blist = alistp;
else {
list[3] = 42; /* this store disappears with -O1 -fstrict-
aliasing */

I'm adding support to GCC for a different PPC floating point unit.
It's similar to the standard PPC FPU in that it supports most of
the same instructions and all operation are in FP registers.
The FPU comes in a single-precision and double-precision variant.
There's also an option of having no FPU
