RE: PR40459
The errors are different between that PR and this one. So, my guess is that
these are not related. That is also a warning, and this is an error.
FWIW, I think this should be a P1.

With -fno-signed-zeroes, a-b*c is transformed to -(b*c-a), which is a machine

This weird side-effect of IPA-SRA is caused by a bug in
compute_inline_parameters which should pass node->decl instead of
current_function_decl to its helper functions. I am about to test the
following patch which f

There is a pass "duplicate_computed_gotos" that should take care of this. Why
does it not work in this case?

Ok, it's simple. We add false aliases to &index to both SMTs of SEntry and
STable because may_alias_p (SEntry, char) returns true as every alias-set
is a subset of alias-set zero.
But then when coming along to addi

GCC 4.1.2 seems to produce the same code.
mov r2, #0
mov r3, r0
strbr2, [r3], #1
strbr2, [r0, #1]
add r0, r3, #2

This is just an internal reminder: we should implement the following suggestion
from Howard on the library reflector. Maybe Chris is interested...

Well, I'm sure it goes wrong in compute_flow_insensitive_aliasing - let me
have a quick look there.

Shorter testcase, fails at -O2 -fno-early-inlining:

TEntry data[2];
} TTable;

When compiling a program with computed goto:s with gcc 4.4.2 it runs
significantly slower (up to a factor 10) than when it is compiled with e.g. gcc
4.1/4.3 with the same optimization flags (-O2 or -O3). A small dummy test
program without header file dependencies is attached.
I am compiling with a

FWIW, I think this code is valid.
The A template parameter in "typename identity::type..." is in a non-deduced
context, so it's argument should not be deduced from there. The argument of A
should be re-used from the d

Combine is doing what it knows best (forming complicated instructions,
addressing modes in this case); to do this it is already damaging the nice
shape of the code after the tree optimizers, and synthesizing things like x+2.
