Most examples would be related to tools generating code.
Suppose you have a software package with several hard-coded fully
optimized assembly file for different targets. Your build system need
to know the current target as well as target ABI to select the correct
assembly file to build it. It even

Hello Everyone,
I contributed the Cilk Plus branch of GCC and I would like to create a
page in GCC Wiki (link: http://gcc.gnu.org/wiki/HomePage) with the information
about this branch and maybe some future work. Can someone please tell me how I
can get write access to the GCC wiki?

It's a failure of optimization.

Ah, I get it now. Ew.

I don't like this. I really cannot imagine any situation for which the
compiler can't resolve SIZE to a compile-time constant

Hi!
This concerns multiple character integer constants, e.g.
'abcd'
as discussed in the C99 standard in subsection 6.4.4.4.
We'll call them "multichars".
First: everybody agrees multichars are non-portable and therefore to
be avoided.
That said, there are real-life situations where they
Hi,
I am trying to find where IRA, is deleting trivial insn like:

The problem I am facing is that I have managed to convince GCC to handle
moves that clobber RCC like:
(parallel [(set reg1 reg2) (clobber rcc)])
However, I am getting loads of insn like:
(parallel [(set r1 r2) (clobb
