Re: Manually set sret parameter

Thank you so much for the help! It seems like the TREE_ADDRESSABLE bit is indeed what we have been looking for. In regards to your questions: Sadly, most of this is barely documented if at all. The rust compiler documentation is... not good. I only know about this because somebody mentioned this

Hi. Let me introduce you Fractal Fir who's a student working on rustc_codegen_gcc for the Google Summer of Code. He found some ABI issues (one related to sret) in rustc_codegen_gcc and wanted to join this discussion in order to share more details about what we want to achieve here. Thanks. Le

Re: Criteria for adding AIX as a secondary platform.

The general criteria for primary, secondary, and tertiary platforms are described on the page to which you linked. The choice of level is decided by the GCC Steering Committee in consultation with the GCC Release Managers and the maintainers for the targets / platforms. AIX is an unusual platform

Criteria for adding AIX as a secondary platform.

Hi All, Would like to know the criteria for adding AIX as a secondary platform. https://gcc.gnu.org/gcc-15/criteria.html Willing to participate in the work needed for the platform to be added as primary and secondary. -- Thanks & Regards, Sangamesh

SLP costing vs. forwardprop

Hi, I am just looking at SLP costing for this program: #include typedef int16_t __attribute__((vector_size(16))) int16x8_t; int16x8_t __attribute__((noinline)) vec_padd(int16x8_t a, int16x8_t b) { const int16x8_t result = { a[0] + a[1], a[2] + a[3], a[4] + a[5], a[6]
