[M3devel] gcc/eh/setjmp

[Jay]

I've been trying sprinkling these bits around, to no avail.
I realize another larger step is to communicate much try/except/finally information down, in order to use the native support (which still stinks on Windows).
I stupidly plumbed the depths of "CG" to communicate the bits down before seeing what was needed..

Folks, try adding -Wunreachable-code to your m3back options and tell me if you don't get loads of warnings.for stuff like: TRY   return Foo();ELSE   return FALSE; I get them on NT386GNU and PPC_DARWIN. Functions with TRY need, in gcc parlance: calls_setjmp and the exception/finally blocks need: has_nonlocal_label and functions with RAISE might need: has_nonlocal_goto Luckily, gcc doesn't seem to act on what it figure out.  - Jay
