[PATCH v3] handle MEM_REF with void* arguments (PR c++/95768)

Attached is another revision of a patch I posted last July to keep the pretty-printer from crashing on MEM_REFs with void* arguments: https://gcc.gnu.org/pipermail/gcc-patches/2020-July/549746.html Besides avoiding the ICE and enhancing the MEM_REF detail and improving its format, this revision

[pushed] Darwin : Adjust defaults for the linker.

Hi, Ideally, the linker will be queried for its version and that will be used to determine capabilities that cannot be discovered from reasonable configuration testing. When building cross tools, this might not be possible, and we have strategies for providing useful defaults. These are adjusted

[pushed] Darwin, Simplify headers 4/5 : Remove redundant headers.

Hi The darwinN.h headers (with the sole exception of darwin7.h, which contains a target macro definition) now only contain values that set fall-backs for cross-compilations, these can be provided from the config.gcc script which means we no longer need the darwinN.h - so delete them. tested as pe

[pushed] Darwin, Simplify headers 3/5 : Delete dead code.

Hi, Darwin defines ASM_OUTPUT_ALIGNED_DECL_COMMON which is used in preference to ASM_OUTPUT_ALIGNED_COMMON, which makes the latter definition dead code. Remove this. tested as part 0 pushed to master Iain gcc/ChangeLog: * config/darwin9.h (ASM_OUTPUT_ALIGNED_COMMON): Delete. --- gcc/co

[pushed] Darwin, Simplify headers 2/5 : Move spec for STACK_CHECK_STATIC_BUILTIN.

Hi We now need a modern (C++11) toolchain to bootstrap GCC, so there's no need to skip the stack protect for Darwin < 9. tested as per part 0, pushed to master Iain gcc/ChangeLog: * config/darwin9.h (STACK_CHECK_STATIC_BUILTIN): Move from here.. * config/darwin.h (STACK_CHECK_ST

[pushed] Darwin, Simplify headers 1/5 : Move LINK_GCC_C_SEQUENCE_SPEC [NFC].

Hi There is no need to make the LINK_GCC_C_SEQUENCE_SPEC conditional on configuration parameters, it is adequately conditionalized on the macosx-version-min. tested as per pwert 0, pushed to master Iain gcc/ChangeLog: * config/darwin10.h (LINK_GCC_C_SEQUENCE_SPEC): Move from her

[pushed] Darwin, Simplify headers 0/5 : Move spec for Darwin 10 unwind stub [NFC].

Hi, The darwinN.h headers were (presumably) introduced to allow specs to be adjusted when there was no mmacosx-version-min handling, or that was considered unreliable. We have version-specific specs for the values that have configuration data, and the version is set in the driver (so may be consi

[pushed] Darwin : Adjust defaults for current bootstrap constraints.

Hi, Part of fixing up headers to handle Darwin20. The toolchain now requires a C++11 compiler to bootstrap and none of the older Darwin toolchains which were based on stabs debugging are suitable. We can simplify the debug setup now. tested on darwin8, 9, 16, 18, 20 x86_64-linux-gnu pushed to m
