It may be that we are only running out of mmapped regions, and other arenas cannot be enlarged sufficiently. (new_heap, malloc_extend_top): Handle top_pad more consistently, i.e. only in new_heap(). 1997-04-13 21:10 Philip Blundell <pjb27@cl.cam.ac.uk> * sysdeps/posix/Makefile: Don't try to build and run mk-stdiolim if cross-compiling. * configure.in: Recognise "...linuxaout" OS names and turn off ELF. * configure.in: Add ARM support. * sysdeps/arm/Implies: New file. * sysdeps/arm/__longjmp.S: New file. * sysdeps/arm/bsd-_setjmp: New file. * sysdeps/arm/bsd-setjmp: New file. * sysdeps/arm/bytesex.h: New file. * sysdeps/arm/fpu_control.h: New file. * sysdeps/arm/jmp_buf.h: New file. * sysdeps/arm/setjmp.h: New file. * sysdeps/arm/sysdep.h: New file. * sysdeps/unix/arm/config.h: New file. 1997-04-14 04:03 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-ieee754/s_cproj.c: New file. * sysdeps/libm-ieee754/s_cprojf.c: New file. * sysdeps/libm-ieee754/s_cprojl.c: New file.
