Hi there,
I was just looking through the history of how some code came about, and
get the impression that DECL_NONSHAREABLE was meant to be removed.
It seems like it was added to solve PR49103, with the idea that it could
be removed once a more robust solution was added.

Hello,
I asked on IRC on Monday but since it didn't get any responses and the
mailing list doesn't require someone paying attention at the moment I
ask I'm asking here too.
I've seen that `expand_builtin_init_trampoline` generates a
`gen_rtx_MEM (BLKmode, ...)` on something returned from `

Hello,
I'm looking into how the unwind mechanism works in order to gather
information to inform how we should eventually handle exceptions in MTE.
I'm currently having a discussion on the llvm-dev list about how HWASAN
handles exceptions, and believe it has relevence.

Hello,
During testing we've noticed the "test for excess errors" check on the
"c-c++-common/builtins.c -Wc++-compat" sometimes passes and sometimes
doesn't.
The cause seems to be a restriction in dejagnu where it stops reading
after a given read if its output buffer is greater than 512000 byt

Hi there,
I'd like to make handling of the __RTL function testcases where the
startwith pass name is either invalid, not used for that optimisation
level, or non-existant more understandable.
Currently a problem with the pass name leaves around state that causes
the compiler to ICE on other fu
I've found a testcase where the stack protector code generated through
`-fstack-protector-all` doesn't actually protect anything.

Hi there,
I'm trying to figure out precisely what NOTE_INSN_FUNCTION_BEG means and
hoping someone here knows.
The gcc internal documentation says it "Appears at the start of the
function body, after the function prologue." but this isn't very
precise, and it seems to not distinguish between th

I've had a look into these, and unfortunately it seems they have the same
problem I've been hitting before.
The use of the TARGET_HARD_REGNO_MODE_OK macro limits all uses of registers in
a given mode (so that we wouldn't be able to use register pairs beginning wit
I think you can use pdp11 as an example, it does two things that are similar to
what you're describing.
One is that it requires SImode to go into an even regno, and indicates that it
uses two registers. See TARGET_HARD_REGNO_MODE_OK and TARGET_HARD_REGNO_NREGS.
The other is that it has one

Hello,
I would like to know what sort of version interoperability is supported
between libatomic and gcc.
Mainly I'm trying to nail down whether it's supported to use a program
compiled with a new version of gcc and linked to an older version of
libatomic.
I suspect this is supported, but wa
