[PATCH v4] tree-optimization/101186 - extend FRE with "equivalence map" for condition prediction

Here's a brief summary on the patch: v4 (this version): - In process_bb's condition-prediction code: update equivalence-heads if value-numbers have changed, otherwise some chances can be lost. v3 (a few minor updates): - Simplify function record_equiv_from_prev_phi_1 by removing an argument. -

Libbacktrace: Fix the use of newline in sed replacement

Hi, Libbacktrace fails to run “make check" on macOS (*-apple-darwin21), where the system make is GNU Make 3.81. But I think it would occur on all platforms that are not ELF and use make < 4. Running `make check` leads to this failure: elf_32.c:144:26: error: extra tokens at end of #undef direct

[pushed] Darwin: Define OBJECT_FORMAT_MACHO.

There are places that we need to make different codegen depending on the object format rather than on the arch. We already have definitions for ELF, COFF etc. this adds one for MACHO. Tested on i686, powerpc, x86_64 and aarch64 Darwin. pushed to master, thanks Iain Signed-off-by: Iain Sandoe g

[pushed] Darwin: Check for that flag-reorder-and-partition.

We were checking whether the flag had been set by the user, but not if it was set to true. Which means that the check fails in its intent when the user puts -fno-reorder-and-partition. Tested on i686, powerpc and x86_64-darwin. Pushed to master, thanks Iain Signed-off-by: Iain Sandoe gcc/Chang

[pushed] Darwin: Update rules for handling alignment of globals.

The current rule was too strict and has not been required since Darwin11. This relaxes the constraint to allow up to 2^28 alignment for non-common entities. Common is still restricted to a maximum aligment of 2^15. When the host is an older version of Darwin ( earlier that 11 ) then the existing
