Today's Activity

Eliminate global state from -fsave-optimization-record
dmalcolm: As work towards fixing PR tree-optimization/87025, this patch eliminates global state from optinfo-emit-json.cc in favor of adding an optional m_json_writer field to dump_context, replacing the m_forcibly_enable_optinfo flag. This allows for writing selftests for the interaction of the JSON-building code with the dumpfile.c code.

S/390: Add a new pattern for r{o,x}sbg
iii: Fixes rXsbg_mode_sXl test failures. Combine used to give us (set (reg:SI 65) (ior:SI (lshiftrt:SI (reg:SI 3 %r3 [ bD.2238 ]) (const_int 2 [0x2])) (reg:SI 2 %r2 [ aD.2237 ]))) but now we get (set (reg:SI 65) (ior:SI (subreg:SI (zero_extract:DI (reg:DI 69) (const_int 32 [0x20]) (const_int 30 [0x1e])) 4) (subreg:SI (reg:DI 68) 4))) or (set (reg:SI 65) (ior:SI (subreg:SI (and:DI (lshiftrt:DI (reg:DI 69) (const_int 2 [0x2])) (const_int 4294967295 [0xffffffff])) 4) (subreg:SI (reg:DI 68) 4))) with an extra subreg, which appears because pseudos, unlike hard registers, can be accessed only using their natural mode. This patch adds a special case for that.

claziss: LP_COUNT register cannot be freely allocated by the compiler as it size, and/or content may change depending on the ARC hardware configuration.

claziss: Use PROFILE_HOOK to add mcount library calls in each toolchain.

[ARC] Add peephole rules to combine store/loads into double store/loads
claziss: Simple peephole rules which combines multiple ld/st instructions into 64-bit load/store instructions.

Implement P0722R3, destroying operator delete
jason: A destroying operator delete takes responsibility for calling the destructor for the object it is deleting; this is intended to be useful for sized delete of a class allocated with a trailing buffer, where the compiler can't know the size of the allocation, and so would pass the wrong size to the non-destroying sized operator delete. gcc/c-family/ - c-cppbuiltin.c (c_cpp_builtins): Define __cpp_impl_destroying_delete.

Implement P0780R2, pack expansion in lambda init-capture
jason: Mostly this was straightforward; the tricky bit was finding, in the instantiation, the set of capture proxies built when instantiating the init-capture.
