2012-04-13bsd-user: fix compile failurePeter Maydell1-0/+1
bsd-user doesn't actually support reserving a memory area for the guest address space, but we need to at least define the reserved_va global so that cpu-all.h's RESERVED_VA macro will work correctly. This fixes a compilation error introduced in commit 39879bb which added a use of RESERVED_VA to h2g_valid().

2012-01-10elf: Improve symbol lookup (optimize, fix for bsd-user)Stefan Weil1-7/+4
Coverity complained about local variable key which was only partially initiated. Only key.st_value was set. As this was also the only part of key which was used in function symfind, the code could be optimized by directly passing a pointer to orig_addr. In bsd-user/elfload.c, fix ec822001a2f26eef8701194714f6482b6d852de2 was missing. This was a simple replacement of > by >= in symfind, so I fixed it here without creating an additional patch.

2011-07-30user: Restore debug usage message for '-d ?' in user mode emulationPeter Maydell1-3/+5
The code which prints the debug usage message on '-d ?' for *-user has to come before the check for "not enough arguments", so that "qemu-foo -d ?" prints the list of possible debug log items rather than the generic usage message.

An empty environment is sometimes useful in user mode. The new option provides it for linux-user and bsd-user (darwin-user still has no environment related options). The patch also adds the documentation for other environment related options. Signed-off-by: Stefan Weil <weil@mail.berlios.de>
2010-10-03Replace most gcc format attributes by macro GCC_FMT_ATTR (format checking)Stefan Weil1-1/+1
Since version 4.4.x, gcc supports additional format attributes. __attribute__ ((format (gnu_printf, 1, 2))) should be used instead of __attribute__ ((format (printf, 1, 2)) because QEMU always uses standard format strings (even with mingw32). The patch replaces format attribute printf / __printf__ by macro GCC_FMT_ATTR which uses gnu_printf if supported. It also removes an #ifdef __GNUC__ (not needed any longer).
