* tcg: make sure NDEBUG is defined before including <assert.h>aurel322009-04-161-6/+7
| | | | | | Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@7122 c046a42c-6fe2-441c-8c8c-71466251a162
* Add a --enable-debug-tcg option to configureaurel322009-04-132-4/+9
| | | | | | | | | | | | | This patch allows DEBUG_TCGV to be defined (and also prevents NDEBUG from being defined) when passing an option to the configure script. This should help to prevent any accidental changes that enable DEBUG_TCGV in tcg/tcg.h from being committed in future, and may help to encourage testing with DEBUG_TCGV enabled.

* tcg: add a CONST flag to TCG helpersaurel322009-04-062-4/+12
| | | | | | | | | | A const function only reads its arguments and does not use TCG globals variables. Hence a call to such a function does not save TCG globals variabes back to their canonical location.

* tcg/x86_64: optimize register allocation orderaurel322009-04-051-10/+9
| | | | | | | | | | | | | | | | | | | | | The beginning of the register allocation order list on the TCG x86_64 target matches the list of clobbered registers. This means that when an helper is called, there is almost always clobbered registers that have to be spilled. The same way register %rsi and %rdi are at the top of the register allocation order list, while they can't be used for load/store operations. This means the data and/or address registers are very often %rsi and %rdi, and their values have to be spilled, and then moved back to another register. This patches changes to the allocation order to avoid those effects. It results in a 8% gain speed in qemu-x86_64 to compress a bzip2 file, and a 6% gain in qemu-system-mips64 to compile a small application.

It's the way qemu_ld64 is translated to arm instructions. tcg_out_ld32_12(s, COND_AL, data_reg, addr_reg, 0); tcg_out_ld32_12(s, COND_AL, data_reg2, addr_reg, 4); Consider case where data_reg==0, data_reg2==1, and addr_reg==0. First load overwrited addr_reg. So let's put an if (data_ref==addr_reg). (Pablo Virolainen) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6808 c046a42c-6fe2-441c-8c8c-71466251a162
