So, at this point, should I proceed with UNSPEC considering the
complications that might arise as Richard points out?

Hello.
The fromfp/fromfpx variants round to integers with a specified number
of bits, to a specified rounding mode. They come with their own
complications as Joseph had stated in an initial mail and expected to
expand them in AArch64 :

All,
this is my first post on these lists, so please bear with me.
My question is about gcc's __attribute__((aligned()). Please consider the
following code:
#include
typedef uint32_t uuint32_t __attribute__((aligned(1)));
uint32_t getuuint32(uint8_t p[]) {
return *(uuint32_t*)p;
}

I don't think that's true. In GCC-9 the doc for 'aligned' attribute has been

See target.def.
You'll need a GCC-specific enum (GCC_FP_INT_*, say) that GCC uses
internally, and a hook that maps between that and FP_INT_*. I'm guessing
that for the likely uses,

I was wondering if anyone could help me investigate a bug I am seeing
in the GCC garbage collector. This bug (which may or may not be PR
89179) is causing a segfault in GCC, but when I try to create a
preprocessed source file, the bug doesn't trigger. The problem is with
the garbage collector try

Hello.
The deadline for final evaluations is 26th of August and there are
certain things that I need to submit along with the code.
A link has to be submitted of the codes that I have written and I am
thinking of doing it as a github gist along with links to commits to
my gcc fork. I know that the
Thank you (and others) for your answers. Now I'm just as smart as before,
however.
Is it a supported, documented, 'long term' feature we can rely on or not?
If yes, I would expect it to be properly documented. If not, never mind.
