[Sbcl-devel] bug 132

[Alexey D. <ade...@co...>]

Hello,

1. It is strange that %CATCH VOP accepts tag only in DESCRIPTOR-REG,
   while THROW accepts also in ANY-REG.

2. Even if these VOPs behave as they do now, it does not protect from
   setting non-portable tag: compiler accepts
   (CATCH (THE (UNSIGNED-BYTE 32) TAG) ...) /boxed value/
   (but forbids (THE (UNSIGNED-BYTE 8))).

This patch fixes %CATCH VOP and provides style warnings (though they
are not very informative--do not include source paths). Alpha backend
should be fixed too.
