Hi everyone. We have some .S functionality that uses x86_64’s cmpxchg16b that we compile with CCAS. We’d like to test for architecture support for this instruction (for k1om and others). Ideally we would like to do this using an AC_COMPILE_IFELSE equivalent for raw .S code, rather than C code with inline asm (as done elsewhere in autoconf-archive) because we have some compiler toolchain issues—sometimes compilers don’t seem to realize that the instruction isn’t supported on the architecture when it is in inline asm. Is there a straightforward way to deal with this as a COMPILE test? RUN tests are problematic because the code will be running on a coprocessor (quasi-cross compiled).
