2012-06-10Revert "build: compile oslib-obj-y once"Blue Swirl2-3/+2
This reverts commit 25f27a4f7160d077d6992e811021b4bc3a82abc1 because of bsd-user breakage. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-06-09target-xtensa: fix CCOUNT for conditional branchesMax Filippov1-0/+2
Taken conditional branches fail to update CCOUNT register because accumulated ccount_delta is reset during translation of non-taken branch. To fix it only update CCOUNT once per conditional branch instruction translation. This fixes guest linux freeze on LTP waitpid06 test.

2012-06-09exec: fix TB invalidation after breakpoint insertion/deletionMax Filippov1-1/+2
tb_invalidate_phys_addr has to be called with the exact physical address of the breakpoint we add/remove, not just the page's base address. Otherwise we easily fail to flush the right TB. This breakage was introduced by the commit f3705d5329 "memory: make phys_page_find() return an unadjusted". This appeared to work for some guest architectures because their cpu_get_phys_page_debug implementation returns full translated physical address, not just the base of the TARGET_PAGE_SIZE-sized page.

2012-06-09w32: Fix broken build (missing include file)Stefan Weil1-4/+0
dump.c was recently added to the code. It unconditionally includes sys/procfs which is not available with MinGW (w32, w64). It looks like this file is not needed at all (tested on Linux), so I removed it completely. Some other include statements are also redundant because they are already included in qemu-common, therefore they were removed, too.

2012-06-09do not include <libutil.h> needlessly or if it doesn't existMichael Tokarev3-19/+7
<libutil.h> and <util.h> on *BSD (some have one, some another) were #included just for openpty() declaration. The only file where this function is actually used is qemu-char.c. In vl.c and net/tap-bsd.c, none of functions declared in libutil.h (login logout logwtmp timdomain openpty forkpty uu_lock realhostname fparseln and a few others depending on version) are used. Initially the code which is currently in qemu-char.c was in vl.c, it has been removed into separate file in commit 0e82f34d077dc2542 Fri Oct 31 18:44:40 2008, but the #includes were left in vl.c. So with vl.c, we just remove includes - libutil.h, util.h and pty.h (which declares only openpty() and forkpty()) from there. The code in net/tap-bsd.c, which come from net/tap.c, had this commit 5281d757efa6e40d74ce124be048b08d43887555 Author: Mark McLoughlin <markmc@redhat.com> Date: Thu Oct 22 17:49:07 2009 +0100 net: split all the tap code out into net/tap.c Note this commit not only moved stuff out of net.c to net/tap.c, but also rewrote large portions of the tap code, and added these completely unnecessary #includes -- as usual, I question why such a misleading commit messages are allowed. Again, no functions defined in libutil.h or util.h on *BSD are used by neither net/tap.c nor net/tap-bsd.c. Removing them. And finally, the only real user for these #includes, qemu-char.c, which actually uses openpty(). There, the #ifdef logic is wrong. A GLIBC-based system has <pty.h>, even if it is a variant of *BSD. So __GLIBC__ should be checked first, and instead of trying to include <libutil.h> or <util.h>, we include <pty.h>. If it is not GLIBC-based, we check for variations between <*util.h> as before. This patch fixes build of qemu 1.1 on Debian/kFreebsd (well, one of the two problems): it is a distribution with a FreeBSD kernel, so it #defines at least __FreeBSD_kernel__, but since it is based on GLIBC, it has <pty.h>, but current version does not have neither <util.h> nor <libutil.h>, which the code tries to include 3 times but uses only once.

sys/procfs is not available everywhere (MingW does not have it). Remove this and more unused or redundant include statements. This fixes the broken build. qerror.h was previously included indirectly.

2012-06-07build: compile oslib-obj-y oncePaolo Bonzini2-2/+3

2012-06-07build: convert libhw to nested Makefile.objsPaolo Bonzini7-147/+150
After this patch, the libhw* directories will have a hierarchy that mimics the source tree. This is useful because we do have a couple of files there that are in the top source directory. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-06-07build: move target-independent hw/ objects to nested Makefile.objsPaolo Bonzini5-38/+44
This patch starts converting the hw/ directory. Some files in hw/ are compiled once, some twice (32-/64-bit), some once per target. Each category is moved in a separate patch. After this patch, the files that are compiled once will show the same hierarchy in the build tree as they do in the source tree, for example hw/qdev.o instead of just qdev.o.

2012-06-07build: adapt qom/Makefile and move it to Makefile.objsPaolo Bonzini3-8/+11
qom/ already used a separate makefile. Convert it to use relative paths, and make it declare both common-obj-y and user-obj-y. This way, the upper makefiles do not need to know that some QOM files are compiled twice. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-06-07build: move rules for nesting to Makefile.objsPaolo Bonzini2-25/+24
At this point we will start adding nesting behavior to other files than Makefile.target. Because Makefile.objs is included by Makefile.target, it is simpler to move the processing of subdirectories there. To enable this, only add per-target files to obj-y. Use a separate variable for the linker dependencies, all-obj-y. This variable includes obj-y and also all objects that are taken from other directories.

This simplifies things, because they will only be included for softmmu targets and because the stubs are taken out-of-line in separate files, which in the future could even be compiled only once. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-06-07build: add rules for nestingPaolo Bonzini1-0/+39
This adds the 'magic' rules that take care of subdirectories. The subdirectory makefiles in the source tree are not complete; they only define some variables (listed in nested-vars) according to the configuration. The magic rules descend into subdirectory makefiles and gather the evaluated values of those variables. The values from all subdirectories are joined together, each prefixed with the subdirectory name, and used by the "real" makefiles. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-06-07build: do not sprinkle around GENERATED_HEADERS dependenciesPaolo Bonzini3-20/+13
Keeping GENERATED_HEADERS dependencies up-to-date everywhere is complex. We can simply make the Makefile depend on them, and they will be built before all other targets. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
