2014-02-08disas: Implement disassembly output for A64Claudio Fontana3-0/+100
Use libvixl to implement disassembly output in debug logs for A64, for use with both AArch64 hosts and targets. Signed-off-by: Claudio Fontana <claudio.fontana@linaro.org> [PMM: * added support for target disassembly * switched to custom QEMUDisassembler so the output format matches what QEMU expects * make sure we correctly fall back to "just print hex" if we didn't build the AArch64 disassembler because of lack of a C++ compiler * rename from 'aarch64' to 'arm-a64' because this is a disassembler for the A64 instruction set * merge aarch64.c and aarch64-cxx.cc into one C++ file * simplify the aarch64.c<->aarch64-cxx.cc interface] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2014-02-08disas/libvixl: Fix upstream libvixl compilation issuesPeter Maydell3-18/+17
Fix various minor issues with upstream libvixl so that it will compile successfully on the platforms QEMU cares about: * remove unused GBytes constant (it clashes with the glib headers) * fix suffixes on constants to use 'LL' for 64 bit constants so we can compile on 32 bit hosts Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <rth@twiddle.net>
2014-02-08disas: Add subset of libvixl sources for A64 disassemblerPeter Maydell15-0/+6620
Add the subset of the libvixl sources that are needed for the A64 disassembler support. These sources come from https://github.com/armvixl/vixl commit 578645f14e122d2b which is VIXL release 1.1. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <rth@twiddle.net>

2013-02-23Replace all setjmp()/longjmp() with sigsetjmp()/siglongjmp()Peter Maydell2-8/+9
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.

2013-02-23disas/i386.c: Add explicit braces round empty for-loop bodyPeter Maydell1-1/+2
Add explicit braces round an empty for-loop body; this fits QEMU style and is easier to read than an inconspicuous semicolon at the end of the line. It also silences a clang warning: disas/i386.c:4723:49: warning: for loop has empty body [-Wempty-body] for (i = 0; tmp[i] == '0' && tmp[i + 1]; i++); ^ disas/i386.c:4723:49: note: put the semicolon on a separate line to silence this warning [-Wempty-body] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

All of universal-obj-y, user-obj-y (right now unused) and common-obj-y can be unified into common-obj-y if we take care of defining CONFIG_SOFTMMU and CONFIG_USER_ONLY in the toplevel makefile. This is similar to how we define symbols for hardware components. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

TCI no longer compiled after commit 76cad71136b7eb371cf2a2a4e1621cfe8d9c769a. The TCI disassembler depends on data structures which are different for each QEMU target, so it cannot be compiled as a universal-obj today.
