This PR updates the SGPR layout to a striped caller/callee-saved design, similar to the VGPR layout. To ensure that s30-s31 (return address), s32 (stack pointer), s33 (frame pointer), and s34 (base pointer) remain callee-saved, the striped layout starts from s40, with a stripe width of 8. The last stripe is 10 wide instead of 8 to avoid ending with a 2-wide stripe. Fixes #113782.
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
