2001-08-09 Benjamin Kosnik <bkoz@redhat.com> * acconfig.h (_GLIBCPP_MEM_LIMITS): Define. * config.h.in: Regenerate. * acinclude.m4 (GLIBCPP_CHECK_SETRLIMIT): Check for setrlimit function. * aclocal.m4: Regenerate. * configure.in: Remove duplicate AM_CONFIG_HEADER. (AM_CONFIG_HEADER): Remove testsuite/testsuite_hooks.h. Only call GLIBCPP_CHECK_SETRLIMIT for native compiles. * configure: Regenerate. * testsuite_hooks.h.in: Move to... * testsuite_hooks.h: Here, include c++config.h. Use it. * Makefile.am (SUBDIRS): Move testsuite to last directory. * Makefile.in: Regenerate. * po/Makefile.am (stamp-po): Add. From-SVN: r44752

// This file provides the following:

|
|
// 1) VERIFY(), via DEBUG_ASSERT, from Brent Verner <brent@rcfile.org>.
|
|
// This file is included in the various testsuite programs to provide
|
|
// #define(able) assert() behavior for debugging/testing. It may be
|
|
// a suitable location for other furry woodland creatures as well.
|
|
//
|
|
// 2) __set_testsuite_memlimit()
|
|
// __set_testsuite_memlimit() uses setrlimit() to restrict dynamic memory
|
|
// allocation. We provide a default memory limit if none is passed by the
|
|
// calling application. The argument to __set_testsuite_memlimit() is the
|
|
// limit in megabytes (a floating-point number). If _GLIBCPP_MEM_LIMITS is
|
|
// #defined before including this header, then no limiting is attempted.
