Hi.I've been told on IRC to use specs to achieve some of the things I want to do in libgccjit (for instance, instead of calling host_detect_local_cpu which doesn't exist when cross-compiling).
I've been having some issues to do so. Can I only call do_spec in specific places?It works OK in lang_specific_pre_link, but I get a segfault in a jit target hook. (I guess this could again be a bug with global variables in libgccjit)
The second issue I have is how can I extract the information I want from the spec I evaluate?
For instance, how could I get the file found by this:
do_spec("%:find-file(lto1)")
?
do_spec only returns an int, so do I need to call some other function?
Thanks for your help.
