Hi,
I am quite surprised I did not catch this before but the new
ipa-param-manipulation does not copy PARM_DECLs when creating artificial
thinks (I think it originally did but then I somehow removed during one
cleanups). Fixed below by adding the capability at the natural place.

If __index_type is a smaller type than size_t, then the result of
size_t(__index_type(-1)) is not equal to size_t(-1), but to an incorrect
value such as size_t(255) or size_t(65535). The old implementation of
variant::index() uses (size_t(__index_type(_M_index + 1)) - 1)
which is always correct,
Hi all,
arm-builtins.o is missing a Makefile dependency on arm_acle_builtins.def
which can cause inconsistent rebuilds
when adding builtins in there.
This patch adds the right Makefile-foo to fix that.
Tested on arm-none-eabi.
Committing to trunk.
Thanks,

The following patch adds define_insn support for xxswapd mnemonic. The

decay_conversion converts a bit-field access to its declared type, which
isn't what we want here; it even has a comment that the caller is expected
to have already used default_conversion to perform integral promotion. This
