-Subject: [PATCH] configure.ac: autodetect 'pause' instruction presence on
- sparc
-
-The change fixes the following build failure on sparc T3 and older CPUs:
-
-```
-sparc-unknown-linux-gnu-gcc ... -O2 -mcpu=niagara2 ... -c rwlock.c
-{standard input}: Assembler messages:
-{standard input}:398: Error: Architecture mismatch on "pause ".
-{standard input}:398: (Requires v9e|v9v|v9m|m8; requested architecture is v9b.)
-make[1]: *** [Makefile:280: rwlock.o] Error 1
-```
-
-`pause` insutruction exists only on `-mcpu=niagara4` (`T4`) and upper.
-
-The change adds `pause` configure-time autodetection and uses it if available.
-config.h.in got new `HAVE_SPARC_PAUSE` knob. Fallback is a fall-through no-op.
-
-Build-tested on:
-
-- sparc-unknown-linux-gnu-gcc (no `pause`, build succeeds)
-- sparc-unknown-linux-gnu-gcc -mcpu=niagara4 (`pause`, build succeeds)
-
