There is no reason to ignore QT_LFLAGS_TDS and QT_LFLAGS_PSQL in static builds. Via LIBS these may end up in QMAKE_PRL_LIBS in QtSql.prl. Also, the isEmpty() tests on these is redundant and only wastes time. Processing of QT_CFLAGS_PSQL should not depend on QT_LFLAGS_PSQL. It no longer seems appropriate to clean up "-lz" here in case of zlib bundled in QtCore. It's reasonable to expect QT_LFLAGS_PSQL to be ready after configure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This results in no change on the Core-i7, but another 2.6% on the Atom (so it's now 8% better than 4-byte loads and 31% better than current code)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The results on i7 are 32% improvement over current code, 13% improvement over 4-byte loads, 6% over the unaligned SSSE3 loads. However, it's about 2.5% slower than pure SSE2 code due to complexity. The results on Atom are 30% improvement over current code, 7% over 4-byte loads, 15% over pure unaligned SSE2 and 9% over unaligned SSSE3.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a different technique of aligning. Instead of reading some bytes before the string, we will read some bytes of the string twice. Best results are only 2% improvement over the unaligned SSE2 on a Core-i7.

| | | | * Update comments in QString about alignment performance.Thiago Macieira2010-08-242-15/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit makes no code change at all. Write down the conclusions from experimenting with the x86 SIMD instructions for faster string comparison routines. Long story short: we're already pretty good. The SSE4.2 string instructions are probably more useful for "implicit-length mode" (that is, the end of the string is marked by a NUL), rather than QString's "explicit-length mode".
| | | | * Major improvements to the comparison functions.Thiago Macieira2010-08-242-188/+1770
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also use the real-world data that I collected. The resulting files are quite large, so I've added to Git only the smallest dump (apparently Teambuilder scanning the environment for "TEAMBUILDER=").

| | | | | | | | | | | | | | | | | | | | | | | | | It's currently slightly worse than SSE2 with prolog aligning (i.e., it's no good)
| | | | * Add an SSSE3 version that uses palignr to align.Thiago Macieira2010-08-242-1/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using a non-SIMD method for aligning, we instead load more bytes from p1 and use the PALIGNR instruction to realign to what we want. The result is that it's bit slower than the non-SIMD comparison, due to the complexity. For strings over 8 QChars wide, it's only slightly worse than the non-SIMD comparison.
| | | | * Add an SSE2 comparison with prologThiago Macieira2010-08-241-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The prolog tries to align p1 to a multiple of 16, so as to run aligned loads, which are faster. Unfortunately, my tests so far indicate that the prolog ends up taking longer than the benefit of having aligned loads.

| | | | | | | | | | | | | | | | | | | | | | | | | This function uses unaligned loads. I'll try to write one with aligned loads later.
