Fix handling of deferred SSA names in modref

Hi, in the testcase we fail to analyze SSA name because flag do_dataflow is set and thus triggers early exist in analyze_ssa_name. Fixed by disabling early exits when handling deferred names. Bootstrapped/regtested x86_64-linux, comitted. gcc/ChangeLog: 2021-12-20 Jan Hubicka PR ipa

[PATCH, rs6000] Implement mffscrni pattern

Hi, I modified the patch according to David and Segher's advice. This patch defines a pattern for mffscrni. If the RN is a constant, it can call gen_rs6000_mffscrni directly. The "rs6000-builtin-new.def" defines prototype for builtin arguments. The pattern "rs6000_set_fpscr_rn" is then broke

On musl, linking against libphobos fails because it requires ucontext but is not explicitly linked against it.

Fix early exit in modref_merge_call_site_flags

Hi, when adding support for static chain and return slot flags I forgot to update early exit condition in modref_merge_call_site_flags. This yields to wrong code as demonstrated by the Fortran testcase attached to PR (which I hope someone will help me to turn into testuite one). Bootstrapped/regt

[PATCH] gcc: pass-manager: Fix memory leak. [PR jit/63854]

This patch fixes a memory leak in the pass manager. In the existing code, the m_name_to_pass_map is allocated in pass_manager::register_pass_name, but never deallocated. This is fixed by adding a deletion in pass_manager::~pass_manager. Moreover the string keys in m_name_to_pass_map are all dynam

Re: [patch, Fortran] IEEE support for aarch64-apple-darwin

Hi FX, Since support for target aarch64-apple-darwin has been submitted for review, it’s time to submit the Fortran part, i.e. enabling IEEE support on that target. The patch has been in use now for several months, in a developer branch shipped by some distros on macOS (including Homebrew).

[PATCH] ix86: Don't match the 'm' constraint on x86_64_general_operand

x86_64_general_operand is different from general_operand for 64-bit target. To avoid LRA selecting a memory operand which doesn't satisfy x86_64_general_operand for 64-bit target: 1. Add a 'BM' constraint which is similar to the 'm' constraint, but checks x86_64_general_operand for integers > 16
