This patch offers several insn-and-split patterns for bitwise AND with
register and constant that cannot fit into a "MOVI Ax, simm12" instruction,
but can be represented as:
i. 1's least significant N bits and the others 0's (17 <= N <= 31)
ii. 1's most significant N bits and the others 0's (1
In Xtensa ISA, there is no single machine instruction that calculates unary
bitwise negation, but a few similar fused instructions are exist:
"BALL Ax, Ay, label" // if ((~Ax & Ay) == 0) goto label;
"BNALL Ax, Ay, label" // if ((~Ax & Ay) != 0) goto label;
These instructions have never be
No need to describe the "false side" conditional insn patterns anymore.

This patch revises the previous implementation of constant synthesis.
First, changed to use define_split machine description pattern and to run
after reload pass, in order not to interfere some optimizations such as
the loop invariant motion.
Second, not only

Just tried TSAN_SUPPORTED=yes with asynchronous unwind tables enabled,
but I got some strange test failures for tls_race.c:

Hi Simon,
thanks for the patch.

thanks for your report.

ah, i understand it... that is Pmode (synonym of SImode) of a memory
address that points to 'u.f'.
thus, the correct handling is to fail the split pattern.

This is the same sort of problem as in PR80204: at present, GCC 11 & 12 assume
that if the
OS version is >= 20, the compiler should see --mmacosx-version-min={major -
9}.{minor -1}.0,
e.g. for OS version 21.3.0 that would be 12.2.0 (the linker sees
