I have unsuccessfully been trying to build liburcu on Debian/m68k. After adding "m68k" as a detected architecture in configure.ac, the build fails with the assembler generating syntax error messages [1]: gcc -DHAVE_CONFIG_H -I. -I../.. -I../../urcu -Wdate-time -D_FORTIFY_SOURCE=2 -I../.. -I../.. -I../../tests/common -g -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -pthread -c -o test_urcu_defer.o test_urcu_defer.c /tmp/ccXHVXOc.s: Assembler messages: /tmp/ccXHVXOc.s:312: Error: syntax error -- statement `add.l %d1,nr_writes@TLSLE+4(%a0)' ignored /tmp/ccXHVXOc.s:440: Error: syntax error -- statement `add.l %d1,nr_writes@TLSLE+4(%a0)' ignored
The invalid asm is related to Thread Local Storage and liburcu has a compat layer that can be enabled at configure for platforms that don't have it. With './configure --disable-compiler-tls' the build succeeds and the regression test suite completes without having to disable optimisations.
