2014-02-17QMP: allow JSON dict arguments in qmp-shellStefan Hajnoczi1-0/+3
qmp-shell hides the QMP wire protocol JSON encoding from the user. Most of the time this is helpful and makes the command-line human-friendly. Some QMP commands take a dict as an argument. In order to express this we need to revert back to JSON notation. This patch allows JSON dict arguments in qmp-shell so commands like blockdev-add and nbd-server-start can be invoked: (QEMU) blockdev-add options={"driver":"file","id":"drive1",...} Note that spaces are not allowed since str.split() is used to break up the command-line arguments first.

2014-02-17hmp: migrate command (without -d) now blocks correctlySoramichi AKIYAMA1-1/+2
This patch fixes a timing issue that migrate command (without -d) does not block in some cases. The original version of hmp.c:hmp_migrate_status_cb checks if the migration status is 'active' or not to detect the completion of a migration. However, if this function is executed when the migration status is stil 'setup' (the status before 'active'), migration command returns immediately even if the user does not specify -d option.

2014-02-17tcg/i386: Use SHLX/SHRX/SARX instructionsRichard Henderson1-11/+50
These three-operand shift instructions do not require the shift count to be placed into ECX. This reduces the number of mov insns required, with the mere addition of a new register constraint. Don't attempt to get rid of the matching constraint, as that's impossible to manipulate with just a new constraint. In addition, constant shifts still need the matching constraint.

This resolves the build issue with building the ROMs on OpenBSD on x86 archs. As of OpenBSD 5.3 the compiler builds PIE binaries by default and thus the whole OS/packages and so forth. The ROMs need to have PIE disabled.

2014-02-15gitignore: anchor all ignored namesMichael Tokarev1-75/+75
by default, patterns/names in .gitignore are applied recursively to all subdirectories. So any name mentioned in .gitignore is ignored in all subdirectores. This is good for, say. object files (*.o), but not good for particular names which should be ignored only in one directory. For example, qemu-img.1 file is generated in the top directory, and it should be ignored only there, not in some subdir. At first, this might not matter much, but we have lots of examples already where it actually does not help at all. For example, top-level .gitignore ignores a file/dir named "patches" (which is very questionable by itself), but it is applied recursively, so git also ignores, for example, debian/patches/ which should not be ignored. So anchor all the names where appropriate. .gitignore should be cleaned up further, which will be addressed in a subsequent patch. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
