2010-02-07Do not use dprintfmalc14-204/+204
dprintf is already claimed by POSIX[1], and on at least one system is implemented as a macro [1] http://www.opengroup.org/onlinepubs/9699919799/functions/dprintf.html Signed-off-by: malc <av1474@comtv.ru>
2010-02-06arm host: fix compiler warningStefan Weil2-27/+0
Compilation for arm (native or cross) results in this warning: fpu/softfloat-native.c: In function ‘float64_round_to_int’: fpu/softfloat-native.c:387: error: control reaches end of non-void function float64_round_to_int uses special assembler code for arm and has no explicit return value. As there is no obvious reason why arm should need special code, all fpu related conditionals were removed. The remaining code is standard (C99) and compiles for arm, too.

2010-02-06tcg-i386: Implement small forward branches.Richard Henderson2-38/+81
There are places, like brcond2, where we know that the destination of a forward branch will be within 127 bytes. Add the R_386_PC8 relocation type to support this. Add a flag to tcg_out_jxx and tcg_out_brcond* to enable it. Set the flag in the brcond2 label_next branches; pass along the input flag otherwise.

2010-02-06Add -static earlier to LDFLAGS for compile_prog()Loïc Minier1-2/+3
Add -static to LDFLAGS earlier as to run the compile_prog() tests with this flags, this will avoid turning on features for which a shared library is available but not a static one. Signed-off-by: Loïc Minier <lool@dooz.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-06Fix missing symbols in .rel/.rela.plt sectionsLoïc Minier2-4/+28
Fix .rel.plt sections in the output to not only include .rel.plt sections from the input but also the .rel.iplt sections and to define the hidden symbols __rel_iplt_start and __rel_iplt_end around .rel.iplt as otherwise we get undefined references to these when linking statically to a multilib libc.a. This fixes the static build under i386. Apply similar logic to rela.plt/.iplt and __rela_iplt/_plt_start/_end to fix the static build under amd64.

2010-02-06configure: fix compilation on hosts without -fstack-protector-allAurelien Jarno1-2/+5
Commit a0f291fc101a7ab3e40850a329da2cc2f2cd1f2d has enabled -fstack-protector-all on all targets, as the configure test is bogus. GCC only emits a warning and not an error if this option is not supported, so the configure scripts doesn't detect the problem. This patch changes the configure script to try the various flags with -Werror in addition to catch the possible warnings. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-02-06target-mips: don't call cpu_loop_exit() from helper.cAurelien Jarno3-8/+22

2010-02-06target-arm: refactor cp15.c13 register accessRiku Voipio2-16/+55
Access the cp15.c13 TLS registers directly with TCG ops instead of with a slow helper. If the the cp15 read/write was not TLS register access, fall back to the cp15 helper. This makes accessing __thread variables in linux-user when apps are compiled with -mtp=cp15 possible. legal cp15 register to acces from linux-user are already checked in cp15_user_ok. While at it, make the cp15.c13 Thread ID registers available only on ARMv6K and newer. Signed-off-by: Riku Voipio <riku.voipio@nokia.com>

2010-02-06target-ppc: change DCR helpers to target_long argumentsAurelien Jarno2-8/+8
The recent transition to always have the DCR helper functions take 32 bit values broke the PPC64 target, as target_long became 64 bits there. This patch changes DCR helpers to target_long arguments, and cast the values to 32 bit when needed.

2010-02-06usb-linux: increase buffer for USB control requestsChristian Krause1-1/+1
The WLAN USB stick ZyXEL NWD271N (0586:3417) uses very large usb control transfers of more than 2048 bytes which won't fit into the buffer of the ctrl_struct. This results in an error message "husb: ctrl buffer too small" and a non-working device. Increasing the buffer size to 8192 seems to be a safe choice.

2010-02-03qdev: Add help for device propertiesMarkus Armbruster1-1/+14
Option "-device DRIVER,?" and monitor command "device_add DRIVER,?" print the supported properties instead of creating a device. The former also terminates the program.

2010-02-03Revert "qdev: Add help for device properties"Markus Armbruster1-13/+2
This reverts commit 2ba6edf0dd740166632df80caa85992b20791a68. The commit has two issues: * When it runs from the monitor, e.g. "device_add e1000,?", it prints to stderr instead of the monitor. * Help looks to callers just like failed device creation. This makes main() exit unsuccessfully on "-device e1000,?". We need to do this differently. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

This reverts commit 922910ce42d15bdb7c2347436b1b5798b5401de4. The commit has four issues: * When it runs from the monitor, e.g. "device_add e1000,mac=?", it prints to stderr instead of the monitor. * Help looks to callers just like failed device creation. This makes main() exit unsuccessfully on "-device e1000,mac=?". * It has an undocumented side effect on -global: "-global e1000.mac=?" prints help, but only when we actually add an e1000 device. * It does not work for properties that accept the value "?". We need to do this differently. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-03qdev: Fix exit code for -device ?Markus Armbruster3-9/+28
Help was shoehorned into device creation, qdev_device_add(). Since help doesn't create a device, it returns NULL, which looks to callers just like failed device creation. Monitor handler do_device_add() doesn't care, but main() exits unsuccessfully. Move help out of device creation, into new qdev_device_help().

2010-02-03qemu-option: Make qemu_opts_foreach() accumulate return valuesMarkus Armbruster1-1/+1
Return the bitwise inclusive or of all return values instead of the last call's value. This lets you find out whether any of the calls returned a non-zero value. No functional change, as existing users either don't care for the value, or pass non-zero abort_on_failure, which breaks the loop on the first non-zero return value.

2010-02-03monitor: Use argument type 'T' for migrate_set_downtimeMarkus Armbruster2-14/+3
Before, it used type 's', which strips quotes and interprets escapes, and is quite inappropriate for QMP. Negative arguments are no flushed to zero. Before, they were cast to uint32_t, which wrecked the sign. Ridiculously large arguments including infinities are now rejected. Before, they were interpreted as zero. Same for NaN.
