* hybrid allocator tuningmread2010-09-302-1/+9
| | | | | | | | | | | | | | | | | | | | | Set various pragmas and defines to tune the hybrid allocator. Performance test was the time takes to allocate or deallocate as appropriate 1,000,000 times from a set of 100,000 pointers, selected at random, with sizes generated randomly with min 2, max 5960, avg 46. The function was exp(8 - log(2 + rand(0..1023))) * rand(1 or 4). The following parameters were chosen: * pragma arm, for ~1.2% * pragma Otime, for ~3% * pragma O2, already the compiler default, just to be sure * all possible slab sizes enabled, for ~1% NB Disabling BTrace would also gain ~1.5%, but that seems like a bad thing to do.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use ARMv6 atomics where available Use OS atomics otherwise Integrate ARMV6 atomics to Symbian builds Use compiler defined macros to detect if ARMv6 instructions are available This defines the QT_HAVE_ARMV6 macro, replacing the way it was defined by the Symbian build system previously in qpainting.pri. qatomic_symbian now uses qatomic_arm or qatomic_armv6 automatically Port armv6 atomics to implement generic atomics interface The inline atomics are not inlined when we build for thumb using RVCT. So there is no performance improvement of using the "inline" versions vs a shared version called through a function call. The generic atomics interface is good for binary compatibility, as the same symbols are exported in all versions now. Changed the fallback generic atomics implementation from the unix one to a symbian specific one using RFastLock (identical code to the windows generic atomics, except for RFastLock replaces Win32 CRITICAL_SECTION) Note: GCCE atomics still need porting Tell git to ignore .lst listing files (produced by sbs/abld listing) ARMv6 support for GCCE compiler and fallback implementation using OS When building corelib with GCCE and -march=armv6, QT_HAVE_ARMV6 will be defined. This patch adds copies of the asm functions in GCC syntax. When building for the Symbian emulator, or ARMv5, then Symbian OS atomic functions are used as a fallback - these are more efficient than the unix atomics, and don't require data import (which the ARMv5 atomics use, but the OS loader doesn't support fully) Symbian OS functions are always used for QBasicAtomicInt::ref / deref, because these are faster than the generic function in all cases. They are machine coded for ARMv6, and are used internally by RFastLock. Reviewed-By: axis Reviewed-By: Brad
* Add the ARMv6 inline assembly code for compiling with RVCT.Thiago Macieira2009-11-131-0/+132
| | | | | | | | | | | | | | | | | | | | | | This is basically a copy & paste of the GCC inline assembly above, switched to the RVCT inline assembly model (which is actually easier to write and understand). I verified that this code compiles and assembles as expected. The output generated by RVCT is pretty much on the mark. However, I have not executed this code yet to see if it performs as expected. To be noted: - when expanding the inline template code, RVCT may be tempted to switch your entire function to ARM mode. Should we add __attribute__((noinline)) to prevent that? - There's no equivalent to GCC inline assembler's clobber, especially of "memory". Also, there's no "volatile" qualifier to the assembly. Does the compiler know it can't reorder the code? Does it know it shouldn't trust the value of the memory after this? My test indicates the code is fine... Reviewed-By: Shane Kearns
