Hi Alexandre,
I built the patch on x86_64-linux and darwin*** (fwiw).

Hi Marc,
Here's version #2 of the patch to recognize bswap32 and bswap64

suggestions and feedback. The test cases now confirm the transformation is
applied
when int is 32 bits and long is 64 bits, and should pass otherwise; the

The motivation for this patch is PR middle-end/85811, a wrong-code
regression entitled "Invalid optimization with fmax, fabs and nan".
The optimization involves assuming max(x,y) is non-negative if (say)
y is non-negative, i.e. max(x,2.0). Unfortunately, this is an invalid
assumption in the prese

Any reason for supporting bit_ior only? Don't plus:c or bit_xor:c
work the same (i.e. use (for op (bit_ior bit_xor plus) ...)?

True. I'm surprised there are modern platforms that don't.
What is it that stands in the way? Lack of support for .set in the
assembler? If that's the case,

Oh, one more thing about this.
Requiring all names to be given in canonical form might alleviate some
