2015-02-21Remove tvb_ from the names of wsutil mempbrk routines.Guy Harris1-3/+3
Routines that don't take a tvbuff as an argument shouldn't have tvb_ in the name. Change-Id: I3550256551e30b3f329cbbfca71ef27c727d29c0 Reviewed-on: https://code.wireshark.org/review/7302 Reviewed-by: Guy Harris <guy@alum.mit.edu>
2015-02-21Rename the slower-but-portable mempbrk to ws_mempbrk_portable_exec().Guy Harris1-2/+2
That parallels ws_mempbrk_sse42_exec(). Change-Id: I1662badc6d1efab5bdd827f29bbad3712464ec43 Reviewed-on: https://code.wireshark.org/review/7301 Reviewed-by: Guy Harris <guy@alum.mit.edu>
2015-02-21Move declarations of internal ws_mempbrk routines to a separate header.Guy Harris1-1/+1
Put the internal routines, which are only to be used by the implementation of the mempbrk functions, to a separate header file, so that they're not exported even in the standard header file.

2015-02-11Combine SSE and pre-compiled patterns for faster pbrkHadriel Kaplan1-28/+32
This combines the SSE4.2 instructions usage, with pre-compiled pattern searching usage, for a faster pbrk search method. Testing against large files of HTTP and SIP, there is about a 5% performance improvement by using pre-"compiled" patterns for guint8_pbrk() instead of passing it the search string and having it build the match array every time. Similar to regular expressions, "compiling" the pattern match array in advance only once and using the "compiled" patterns for the searches is faster than compiling it every time.

2015-01-30Disable SSE4.2 _ws_mempbrk_sse42 only for older Apple compilersHadriel Kaplan1-3/+13
This is a longer term fix to disable _ws_mempbrk_sse42 in older Apple compilers, which the buildbots currently use. This fix is the longer-term fix for the temprorary one introduced in g9a366b04/I2e438ff29.

2014-06-10CPUID improvementsJakub Zawadzki1-7/+4
- Make ws_cpuid() return boolean when CPUID is support or no, this way it's easier for caller to determinate if it works (and can use cpuinfo[X] or no). - Add function ws_cpuid_sse42(), use it in ws_mempbrk() [cached] & version information.

2014-06-09Add sse4.2 optimized function ws_mempbrk_sse42()Jakub Zawadzki1-0/+74
In text protocols, like SIP, lot of time is spend guint8_pbrk(), assume that text is not binary (no NULs), and use SSE4.2 pcmpistri instruction. Also move & rename guint8_pbrk() from tvbuff.c as _ws_mempbrk. HAVE_SSE42 must be defined to use _ws_mempbrk_sse42() only activaded for Windows currently.
