Hi Harald,
It looks good to me. OK for mainline. You might even consider backporting
to 11-branch.
Best regards

Reference with cv-qualifiers should be ignored instead of causing an error
because standard accepts cv-qualified references introduced by typedef which
is ignored.
Therefore, the fix prevents GCC from reporting error by not setting variable
"bad_quals" in case the reference is introduced by typed
Currently, the enums from define_c_enum and define_enum can only
has values one by one from 0.
In fact we can support the behaviour just like C, aka like
(define_enum "mips_isa" [mips1=1 mips2 mips32=32 mips32r2]),
then we can get
enum mips_isa {
MIPS_ISA_MIPS1 = 1,
MIPS_ISA_MIPS2 = 2,
Currently mips-cpu.defs and mips.h are using hardcoded numbers
for isa level.
Let's replace them with more readable enum mips_isa.
gcc/ChangeLog:
* config/mips/mips.md: define_enum "mips_isa".
* config/mips/mips.h (struct mips_cpu_info): use enum
instead of int for 'isa'
Currently, the asm output file for MIPS has no rev info.
It can make some trouble, for example:
assembler is mips1 by default,
gcc is fpxx by default.
To assemble the output of gcc -S, we have to pass -mips2
to assembler.

* gcc/config/mips/mips.c (mips_module_isa_name): New

When the path is already absolute, the call to current_path() is
wasteful, because operator/ will ignore the left operand anyway.

Removing the allocator specialization for the versioned namespace
breaks _Extptr_allocator because the allocator

incomplete type. It wrong to remove that specialization anyway, because
it is still needed pre-C++20.

Hi,
this should be final bit of the fancy access merging. We limit number of
accesses to 16 and on the overflow we currently just throw away the whole
table. This patch instead looks for closest pair of entries in the table and
merge them (losing some precision). This is not very often during no

Good, but there is something like "mips_isa_rev >= 32 && mips_isa_rev <
64" in mips.h and netbsd.h. Not
Hi
Before Darwin11 there is no strndup in libc. This test fails with
warning output because of that - so skip it on these versions (since
they are not able to use strndup anyway).
tested across the Darwin range and on x86_64, powerpc64 linux.
pushed to master, thanks
