[PR debug/77773] segfault when compiling __simd64_float16_t with -g

The following one-liner segfaults on arm-eabi when compiled with -mfloat-abi=hard -g: __simd64_float16_t usingit; The problem is that the pretty printer (in simple_type_specificer()) is dereferencing a NULL result from c_common_type_for_mode: int prec = TYPE_PRECISION (t);

Fix MIPS port WRT sprintf and fallthru warnings

The fallthrus in mips16_constant_cost are pretty obvious. One buffer overflow in mips16_build_call_stub and one obvious fallthru comment adjustment in mips16_build_call_stub. The usual stuff. Installing. jeff commit c03f0de027e1079edd02e3494601c6def50dbac1 Author: law Date: Wed Oct 26

Fix sh port WRT fallthru

This adjusts existing fallthru comments and adds some new ones. I couldn't convince myself the original code in movsicc was correct, It looks like we properly reverse the condition, but not the operands in the case of LT/LE/LEU/LTU. But then we do almost the same th ing in sh_emit_scc_to_t

[nvptx] propagating conditionals in worker-vector partitioned loops

Currently, the nvptx backend is only neutering the worker axis when propagating variables used in conditional expressions across the worker and vector axes. That's a problem with the worker-state spill and fill propagation implementation because all of the vector threads in worker 0 all write the t

[PATCH], Allow SImode to go into VSX registers on PowerPC ISA 2.07 (power8) and above

PowerPC GCC has traditionally only allowed DImode to go into FPR registers (and now VSX registers) in order to allow floating point conversions. Conversions to/from SImode have always had to deal with special UNSPECs to allow the generation of the LFIWAX, LXSIWAX, LFIWZX, LXSIWZX, STFIWX, and STXS

Re: [PATCH], Allow SImode to go into VSX registers on PowerPC ISA 2.07 (power8) and above

I forgot to mention, I will be working on a follow-on patch to this that enables QImode and HImode to go in the vector registers for ISA 3.0, since ISA 3.0 now adds load (with zero extend) and store instructions for those types. I probably also will update vector extract for the case where the sma

[RFC PATCH] expand_strn_compare should attempt expansion even if neither string is constant

I'm currently working on a builtin expansion of strncmp for powerpc similar to the one for memcmp I checked recently. One thing I encountered is that the code in expand_strn_compare will not attempt to expand the cmpstrnsi pattern at all if neither string parameter is a constant string. This doesn'
