2014-10-24disas/libvixl/a64/instructions-a64.h: Remove unused constantsChen Gang
The instructions-a64.h header defines a number of floating point constants whose initializers are function calls. gcc 5 will warn if these constants are not used by the C or C++ file which includes the header, because they imply a runtime cost. Since for the files QEMU uses from libvixl we don't use these constants at all, just remove them. Upstream intend to fix these by shifting to an 'extern const' in the header plus definition in a suitable source file, so we can drop this patch when we sync with the upcoming libvixl 1.7. The related compiling error: CXX disas/arm-a64.o In file included from /upstream/qemu/disas/libvixl/a64/disasm-a64.h:32:0, from disas/arm-a64.cc:20: disas/libvixl/a64/instructions-a64.h:98:13: error: 'vixl::kFP32PositiveInfinity' defined but not used [-Werror=unused-variable] const float kFP32PositiveInfinity = rawbits_to_float(0x7f800000); ^ disas/libvixl/a64/instructions-a64.h:99:13: error: 'vixl::kFP32NegativeInfinity' defined but not used [-Werror=unused-variable] const float kFP32NegativeInfinity = rawbits_to_float(0xff800000); ^ disas/libvixl/a64/instructions-a64.h:100:14: error: 'vixl::kFP64PositiveInfinity' defined but not used [-Werror=unused-variable] const double kFP64PositiveInfinity = ^ disas/libvixl/a64/instructions-a64.h:102:14: error: 'vixl::kFP64NegativeInfinity' defined but not used [-Werror=unused-variable] const double kFP64NegativeInfinity = ^ disas/libvixl/a64/instructions-a64.h:107:21: error: 'vixl::kFP64SignallingNaN' defined but not used [-Werror=unused-variable] static const double kFP64SignallingNaN = ^ disas/libvixl/a64/instructions-a64.h:109:20: error: 'vixl::kFP32SignallingNaN' defined but not used [-Werror=unused-variable] static const float kFP32SignallingNaN = rawbits_to_float(0x7f800001); ^ disas/libvixl/a64/instructions-a64.h:112:21: error: 'vixl::kFP64QuietNaN' defined but not used [-Werror=unused-variable] static const double kFP64QuietNaN = ^ disas/libvixl/a64/instructions-a64.h:114:20: error: 'vixl::kFP32QuietNaN' defined but not used [-Werror=unused-variable] static const float kFP32QuietNaN = rawbits_to_float(0x7fc00001); ^ disas/libvixl/a64/instructions-a64.h:117:21: error: 'vixl::kFP64DefaultNaN' defined but not used [-Werror=unused-variable] static const double kFP64DefaultNaN = ^ disas/libvixl/a64/instructions-a64.h:119:20: error: 'vixl::kFP32DefaultNaN' defined but not used [-Werror=unused-variable] static const float kFP32DefaultNaN = rawbits_to_float(0x7fc00000); ^ cc1plus: all warnings being treated as errors make: *** [disas/arm-a64.o] Error 1 Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> [PMM: Rewrote the commit message a little] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2014-07-08disas/libvixl: prepend the include path of libvixl header filesStefano Stabellini
Currently the Makefile of disas/libvixl appends -I$(SRC_PATH)/disas/libvixl to QEMU_CFLAGS. As a consequence C++ files that #include "utils.h", such as disas/libvixl/a64/instructions-a64.cc, are going to look for utils.h on all the other include paths first. When building QEMU as part of the Xen make system, another unrelated utils.h file is going to be chosen for inclusion, causing a build failure: In file included from disas/libvixl/a64/instructions-a64.cc:27:0: /qemu/disas/libvixl/a64/instructions-a64.h:88:64: error: 'rawbits_to_float' was not declared in this scope const float kFP32PositiveInfinity = rawbits_to_float(0x7f800000); Fix the problem by prepending (rather than appending) the libvixl include path to QEMU_CFLAGS.

2013-02-23Replace all setjmp()/longjmp() with sigsetjmp()/siglongjmp()Peter Maydell
The setjmp() function doesn't specify whether signal masks are saved and restored; on Linux they are not, but on BSD (including MacOSX) they are. We want to have consistent behaviour across platforms, so we should always use "don't save/restore signal mask" (this is also generally going to be faster). This also works around a bug in MacOSX where the signal-restoration on longjmp() affects the signal mask for a completely different thread, not just the mask for the thread which did the longjmp. The most visible effect of this was that ctrl-C was ignored on MacOSX because the CPU thread did a longjmp which resulted in its signal mask being applied to every thread, so that all threads had SIGINT and SIGTERM blocked. The POSIX-sanctioned portable way to do a jump without affecting signal masks is to siglongjmp() to a sigjmp_buf which was created by calling sigsetjmp() with a zero savemask parameter, so change all uses of setjmp()/longjmp() accordingly. [Technically POSIX allows sigsetjmp(buf, 0) to save the signal mask; however the following siglongjmp() must not restore the signal mask, so the pair can be effectively considered as "sigjmp/longjmp which don't touch the mask".] For Windows we provide a trivial sigsetjmp/siglongjmp in terms of setjmp/longjmp -- this is OK because no user will ever pass a non-zero savemask. The setjmp() uses in tests/tcg/test-i386.c and tests/tcg/linux-test.c are left untouched because these are self-contained singlethreaded test programs intended to be run under QEMU's Linux emulation, so they have neither the portability nor the multithreading issues to deal with.
