2012-01-10elf: Improve symbol lookup (optimize, fix for bsd-user)Stefan Weil
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.

2011-12-10bsd_user: Fix potential null pointer dereferenceStefan Weil
This bug was spotted by cppcheck. Using g_try_malloc0 (as does the linux-user code) fixes this. v2: Use g_free in bsdload.c, too. Thanks to Peter Maydell for this hint. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-08-05Avoid allocating TCG resources in non-TCG modeJan Kiszka
Do not allocate TCG-only resources like the translation buffer when running over KVM or XEN. Saves a "few" bytes in the qemu address space and is also conceptually cleaner. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-07-30user: Restore debug usage message for '-d ?' in user mode emulationPeter Maydell
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. (This was inadvertently broken in commit c235d73.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>

2011-06-15Command line support for altering the log file locationMatthew Fernandez
Add command line support for logging to a location other than /tmp/qemu.log. With logging enabled (command line option -d), the log is written to the hard-coded path /tmp/qemu.log. This patch adds support for writing the log to a different location by passing the -D option.

2010-10-05Add new user mode option -ignore-environmentStefan Weil
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 Weil
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).
