* Revert change I7af83e21c64d217c6b28bf6cb5ee2e2f23182c95 to fix Froyo build.Vladimir Chtchetkine2010-04-021-8/+0
| | | | | | | | | Apparently, that change that supposedly fixed AT-related ARMv7 bug broke DexOpt step in the build process, resulting in trashed files that crash the device. Rolling this change back to fix Froyo, until cause of the DexOpt breaking has been found and fixed Change-Id: I33b417fcbd65767f7cfe60f5fb5ffa32610b4852
* Fixes for obvious ARMv7 bugs in emulator.Vladimir Chtchetkine2010-03-231-0/+8
| | | | | | | | | | | | | | This CL doesn't fix ARMv7 problems in the emulator (emulated system still crashes, although with these fixes it crashes much later than without them), however, this CL fixes real bugs related to IT block translations. In particular, it fixes: - Wrong ITSTATE calculation on condition that gen_intermediate_code_internal is called with search_pc parameter set to 1. In the original code ITSTATE was blindly inherited from the CPU's condexec_bits field, without consideration that translation could be performed starting from an address that has nothing to do with the current ITSTATE.

* Finally fix ARMv7 NEON emulation.David 'Digit' Turner2009-10-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The real problem was the size of the static intermediate TCG opcode buffer. Due to its SIMD nature, a single Neon instruction can generate a very large number of corresponding TCG opcodes. Using lots of Neon instructions in a big looop like the one we have in our ARMv7-optimized memcpy did generate enough opcodes to overwrite the static gen_opc_buf buffer, resulting in overwrites into the following global buffer (gen_opparam_buf) corresponding to opcode parameters. The end result was generation of really broken host machine code, and completely unreliable emulation, including potential assertion failure in the liveness analysis pass. This patch does the following: - bumps the buffer size from 512 to 2048 - adds sanity checks that will abort the emulator if another similar overwrite is detected before machine code is generated. - remove the previous hack where we disabled the liveness analysis pass for ARMv7 Note that fixing the code generator to not use a static buffer is not trivial at this point, and that we much prefer to stay true to the upstream sources at the moment. Keep in mind that a previous patch also fixed a bug in the ARM->TCG translator (typo required changing a 0 into a 1) which affected Neon instructions too. I can't believe I just lost 2 weeks of my life on that bug :-(
* Merge upstream QEMU 10.0.50 into the Android source tree.David 'Digit' Turner2009-09-141-25/+35
| | | | | | | | | | | | | | | | | | | This change integrates many changes from the upstream QEMU sources. Its main purpose is to enable correct ARMv6 and ARMv7 support to the Android emulator. Due to the nature of the upstream code base, this unfortunately also required changes to many other parts of the source. Note that to ensure easier integrations in the future, some source files and directories that have heavy Android-specific customization have been renamed with an -android suffix. The original files are still there for easier integration tracking, but *never* compiled. For example: net.c net-android.c qemu-char.c qemu-char-android.c slirp/ slirp-android/ etc... Tested on linux-x86, darwin-x86 and windows host machines.
