acconfig.h: New ENABLE flags: TREE_CHECKING, RTL_CHECKING, GC_CHECKING, GC_ALWAYS_COLLECT.
1999-12-26 Zack Weinberg <zack@wolery.cumb.org>
* acconfig.h: New ENABLE flags: TREE_CHECKING, RTL_CHECKING,
GC_CHECKING, GC_ALWAYS_COLLECT.
* configure.in: Allow --enable-checking with an argument
listing check modes to enable.
* config.in, configure: Rebuilt.
* ggc-page.c, ggc-simple.c: Define GGC_POISON (and
GGC_ALWAYS_VERIFY for ggc-simple.c) only if
ENABLE_GC_CHECKING. Define GGC_ALWAYS_COLLECT only if
ENABLE_GC_ALWAYS_COLLECT.
* rtl.h, rtl.c: Change ENABLE_CHECKING to ENABLE_RTL_CHECKING
throughout.
* tree.h, tree.c: Change ENABLE_CHECKING to
ENABLE_TREE_CHECKING throughout.
* cp-tree.h: Replace ENABLE_CHECKING with ENABLE_TREE_CHECKING
throughout.
