2015-02-12tcg: Move some opcode generation functions out of lineRichard Henderson
Some of these functions are really quite large. We have a number of things that ought to be circularly dependent, but we duplicated code to break that chain for the inlines. This saved 25% of the code size of one of the translators I examined. Reviewed-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de> Signed-off-by: Richard Henderson <rth@twiddle.net>

2014-08-12trace: [tcg] Define TCG tracing helper routinesLluís Vilanova
Generates file "trace/generated-helpers.c" with TCG helper definitions to trace events in guest code at execution time. The helpers ('helper_trace_${event}_exec_proxy') cast the TCG-compatible native argument types to their original types (as defined in "trace-events") and call the tracing routine ('trace_${event}_exec').

2014-08-12trace: install simpletrace SystemTap tapsetStefan Hajnoczi
The simpletrace SystemTap tapset outputs simpletrace binary traces for SystemTap probes. This is useful because SystemTap has no default way to format or store traces. The simpletrace SystemTap tapset provides an easy way to store traces. The simpletrace.py tool or custom Python scripts using the simpletrace.py API can analyze SystemTap these traces: $ ./configure --enable-trace-backends=dtrace ... $ make && make install $ stap -e 'probe qemu.system.x86_64.simpletrace.* {}' \ -c qemu-system-x86_64 >/tmp/trace.out $ scripts/simpletrace.py --no-header trace-events /tmp/trace.out g_malloc 4.531 pid=15519 size=0xb ptr=0x7f8639c10470 g_malloc 3.264 pid=15519 size=0x300 ptr=0x7f8639c10490 g_free 5.155 pid=15519 ptr=0x7f8639c0f7b0 Note that, unlike qemu-system-x86_64.stp and qemu-system-x86_64.stp-installed, only one file is needed since the simpletrace SystemTap tapset does not reference the QEMU binary by path. Therefore it doesn't matter whether the QEMU binary is installed or not. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2014-07-01configure: Fix -lm test, so that tools can be compiled on hosts that require -lmAlexey Kardashevskiy
The existing test whether "-lm" needs to be included or not is insufficient as it reports false negative on Fedora20/ppc64. This happens because sin(0.0) is a constant value which compiler can safely throw away and therefore there is no need to add "-lm". As the result, qemu-nbd/qemu-io/qemu-img tools cannot compile. This adds a global variable and uses it in the test to prevent from optimization.

2014-06-09trace: Multi-backend tracingLluís Vilanova
Adds support to compile QEMU with multiple tracing backends at the same time. For example, you can compile QEMU with: $ ./configure --enable-trace-backends=ftrace,dtrace Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system. This patch allows having both available without recompiling QEMU. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2014-02-20rules.mak: fix $(obj) to a real relative pathFam Zheng
Makefile.target includes rule.mak and unnested common-obj-y, then prefix them with '../', this will ignore object specific QEMU_CFLAGS in subdir Makefile.objs: $(obj)/curl.o: QEMU_CFLAGS += $(CURL_CFLAGS) Because $(obj) here is './block', instead of '../block'. This doesn't hurt compiling because we basically build all .o from top Makefile, before entering Makefile.target, but it will affact arriving per-object libs support. The starting point of $(obj) is passed in as argument of unnest-vars, as well as nested variables, so that different Makefiles can pass in a right value.

2013-06-11dump: Drop qmp_dump_guest_memory() stub and build for all targetsAndreas Färber
qmp_dump_guest_memory() calls dump_init() and returns an Error when cpu_get_dump_info() returns an error, as done by the stub. So there is no need to have a stub for qmp_dump_guest_memory(). Enable the documentation of the always-present dump-guest-memory command. That way we can drop CONFIG_HAVE_CORE_DUMP and leave configure completely out of the picture for target CPU features.

2013-06-11memory_mapping: Drop qemu_get_memory_mapping() stubAndreas Färber
dump.c:dump_init() never checked for the return code anyway. If paging is not enabled, it will fall back to an identity map. If paging is enabled and getting memory mapping list is not implemented, qemu_get_guest_memory_mapping() will return an error. Since the targets not implementing memory mapping also don't implement dump support, we will not reach this code today and can worry about changing cpu_paging_enabled() default when the need arises.

2012-11-18build: replace weak symbols with a static libraryPaolo Bonzini
Weak symbols were a nice idea, but they turned out not to be a good one. Toolchain support is just too sparse, in particular llvm-gcc is totally broken. This patch uses a surprisingly low-tech approach: a static library. Symbols in a static library are always overridden by symbols in an object file. Furthermore, if you place each function in a separate source file, object files for unused functions will not be taken in. This means that each function can use all the dependencies that it needs (especially QAPI stuff such as error_setg). Thus, all stubs are placed in separate object files and put together in a static library. The library then is linked to all programs.
