Subject: Turn on incremental collection in gctest also if DEFAULT_VDB or MANUAL_VDB
X-Git-Tag: v8.0.0~201
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=79249057;p=gc

Turn on incremental collection in gctest also if DEFAULT_VDB or MANUAL_VDB

* tests/test.c [DEFAULT_VDB] (TEST_DEFAULT_VDB): Define (before include
gc.h).
* tests/test.c [!GC_DISABLE_INCREMENTAL] (main): Call
GC_enable_incremental also if MANUAL_VDB or TEST_DEFAULT_VDB; print
message about emulating dirty bits with mprotect only if MPROTECT_VDB.
