* bsd-user: align use of mmap_lock to that of linux-userAlex Bennée2017-03-281-12/+1Star
| | | | | | | | | | | | | | The introduction of stricter mmap_lock checking in translate-all broke the BSD user build. The working mmap_lock functions were hidden behind CONFIG_USE_NPTL which is never defined. This patch brings them inline with linux-user. Despite the disapearence of the comment "We aren't threadsafe to start with..." this doesn't make bsd-user so. It will still need the rest of the fixes that have been done in linux-user ported over.

* configure: remove CygwinPaolo Bonzini2017-03-201-5/+0Star
| | | | | | | | | | | | | The Cygwin target is really compiling for native Win32 with -mno-cygwin. Except, GCC 4.7.0 has finally removed the long deprecated -mno-cygwin option, and that happened about five years ago. Let it rest in peace.

* translate-all: add DEBUG_LOCKING assertsAlex Bennée2016-10-311-0/+5
| | | | | | | | | | | | | | | | | | | | | This adds asserts to check the locking on the various translation engines structures. There are two sets of structures that are protected by locks. The first the l1map and PageDesc structures used to track which translation blocks are associated with which physical addresses. In user-mode this is covered by the mmap_lock. The second case are TB context related structures which are protected by tb_lock which is also user-mode only. Currently the asserts do nothing in SoftMMU mode but this will change for MTTCG.

* bsd-user/mmap.c: Don't try to override g_malloc/g_freePeter Maydell2014-06-111-60/+0Star
| | | | | | | | | | | | | | | | | | Trying to override the implementations of g_malloc and g_free is a really bad idea -- it means statically linked builds fail to link (because of the multiple definitions provided by this file and by glib), and non-statically linked builds segfault as soon as they try to do anything more complicated than printing the usage message. Remove these overridden versions and just use the glib ones. This is sufficient that bsd-user can run basic x86-64 binaries on OpenBSD again; FreeBSD and NetBSD seem to have further issues.
