* Add more directives to benchmark input filesSiddhesh Poyarekar2013-10-0720-131/+160
| | | | | | | | | | | | | | | | | | | | | | This patch adds some more directives to the benchmark inputs file, moving functionality from the Makefile and making the code generation script a bit cleaner. The function argument and return types that were earlier added as variables in the makefile and passed to the script via command line arguments are now the 'args' and 'ret' directive respectively. 'args' should be a colon separated list of argument types (skipped if the function doesn't accept any arguments) and 'ret' should be the return type. Additionally, an 'includes' directive may have a comma separated list of headers to include in the source. For example, the pow input file now looks like this: 42.0, 42.0 1.0000000000000020, 1.5 I did this to unclutter the benchtests Makefile a bit and eventually eliminate dependency of the tests on the Makefile and have tests depend on their respective include files only.

* PowerPC LE memchr and memrchrAlan Modra2013-10-047-382/+422
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00105.html Like strnlen, memchr and memrchr had a number of defects fixed by this patch as well as adding little-endian support. The first one I noticed was that the entry to the main loop needlessly checked for "are we done yet?" when we know the size is large enough that we can't be done. The second defect I noticed was that the main loop count was wrong, which in turn meant that the small loop needed to handle an extra word. Thirdly, there is nothing to say that the string can't wrap around zero, except of course that we'd normally hit a segfault on trying to read from address zero. Fixing that simplified a number of places: - /* Are we done already? */ - addi r9,r8,8 - cmpld r9,r7 - bge L(null) becomes + cmpld r8,r7 + beqlr However, the exit gets an extra test because I test for being on the last word then if so whether the byte offset is less than the end. Overall, the change is a win. Lastly, memrchr used the wrong cache hint. * sysdeps/powerpc/powerpc64/power7/memchr.S: Replace rlwimi with insrdi. Make better use of reg selection to speed exit slightly. Schedule entry path a little better. Remove useless "are we done" checks on entry to main loop. Handle wrapping around zero address. Correct main loop count. Handle single left-over word from main loop inline rather than by using loop_small. Remove extra word case in loop_small caused by wrong loop count. Add little-endian support. * sysdeps/powerpc/powerpc32/power7/memchr.S: Likewise. * sysdeps/powerpc/powerpc64/power7/memrchr.S: Likewise.

| | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00104.html One of the things I noticed when looking at power7 timing is that rlwimi is cracked and the two resulting insns have a register dependency. That makes it a little slower than the equivalent rldimi. * sysdeps/powerpc/powerpc64/memset.S: Replace rlwimi with insrdi.

| | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00103.html LIttle-endian support for memcpy. I spent some time cleaning up the 64-bit power7 memcpy, in order to avoid the extra alignment traps power7 takes for little-endian. It probably would have been better to copy the linux kernel version of memcpy. * sysdeps/powerpc/powerpc32/power4/memcpy.S: Add little endian support. * sysdeps/powerpc/powerpc32/power6/memcpy.S: Likewise. * sysdeps/powerpc/powerpc32/power7/memcpy.S: Likewise. * sysdeps/powerpc/powerpc32/power7/mempcpy.S: Likewise. * sysdeps/powerpc/powerpc64/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power4/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power6/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/mempcpy.S: Likewise.

* PowerPC LE memcmpAlan Modra2013-10-045-1893/+3464
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00102.html This is a rather large patch due to formatting and renaming. The formatting changes were to make it possible to compare power7 and power4 versions of memcmp. Using different register defines came about while I was wrestling with the code, trying to find spare registers at one stage. I found it much simpler if we refer to a reg by the same name throughout a function, so it's better if short-term multiple use regs like rTMP are referred to using their register number. I made the cr field usage changes when attempting to reload rWORDn regs in the exit path to byte swap before comparing when little-endian. That proved a bad idea due to the pipelining involved in the main loop; Offsets to reload the regs were different first time around the loop.. Anyway, I left the cr field usage changes in place for consistency. Aside from these more-or-less cosmetic changes, I fixed a number of places where an early exit path restores regs unnecessarily, removed some dead code, and optimised one or two exits. * sysdeps/powerpc/powerpc64/power7/memcmp.S: Add little-endian support. Formatting. Consistently use rXXX register defines or rN defines. Use early exit labels that avoid restoring unused non-volatile regs. Make cr field use more consistent with rWORDn compares. Rename regs used as shift registers for unaligned loop, using rN defines for short lifetime/multiple use regs. * sysdeps/powerpc/powerpc64/power4/memcmp.S: Likewise. * sysdeps/powerpc/powerpc32/power7/memcmp.S: Likewise. Exit with addi 1,1,64 to pop stack frame. Simplify return value code. * sysdeps/powerpc/powerpc32/power4/memcmp.S: Likewise.
* PowerPC LE strchrAlan Modra2013-10-047-74/+228
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00101.html Adds little-endian support to optimised strchr assembly. I've also tweaked the big-endian code a little. In power7/strchr.S there's a check in the tail of the function that we didn't match 0 before finding a c match, done by comparing leading zero counts. It's just as valid, and quicker, to compare the raw output from cmpb. Another little tweak is to use rldimi/insrdi in place of rlwimi for the power7 strchr functions. Since rlwimi is cracked, it is a few cycles slower. rldimi can be used on the 32-bit power7 functions too. * sysdeps/powerpc/powerpc64/power7/strchr.S (strchr): Add little-endian support. Correct typos, formatting. Optimize tail. Use insrdi rather than rlwimi. * sysdeps/powerpc/powerpc32/power7/strchr.S: Likewise. * sysdeps/powerpc/powerpc64/power7/strchrnul.S (__strchrnul): Add little-endian support. Correct typos. * sysdeps/powerpc/powerpc32/power7/strchrnul.S: Likewise. Use insrdi rather than rlwimi. * sysdeps/powerpc/powerpc64/strchr.S (rTMP4, rTMP5): Define. Use in loop and entry code to keep "and." results. (strchr): Add little-endian support. Comment. Move cntlzd earlier in tail. * sysdeps/powerpc/powerpc32/strchr.S: Likewise.
* PowerPC LE strcpyAlan Modra2013-10-045-3/+85
| | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00100.html The strcpy changes for little-endian are quite straight-forward, just a matter of rotating the last word differently. I'll note that the powerpc64 version of stpcpy is just begging to be converted to use 64-bit loads and stores.. * sysdeps/powerpc/powerpc64/strcpy.S: Add little-endian support: * sysdeps/powerpc/powerpc32/strcpy.S: Likewise. * sysdeps/powerpc/powerpc64/stpcpy.S: Likewise. * sysdeps/powerpc/powerpc32/stpcpy.S: Likewise.
* PowerPC LE strcmp and strncmpAlan Modra2013-10-049-81/+393
| | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00099.html More little-endian support. I leave the main strcmp loops unchanged, (well, except for renumbering rTMP to something other than r0 since it's needed in an addi insn) and modify the tail for little-endian. I noticed some of the big-endian tail code was a little untidy so have cleaned that up too. * sysdeps/powerpc/powerpc64/strcmp.S (rTMP2): Define as r0. (rTMP): Define as r11. (strcmp): Add little-endian support. Optimise tail. * sysdeps/powerpc/powerpc32/strcmp.S: Similarly. * sysdeps/powerpc/powerpc64/strncmp.S: Likewise. * sysdeps/powerpc/powerpc32/strncmp.S: Likewise. * sysdeps/powerpc/powerpc64/power4/strncmp.S: Likewise. * sysdeps/powerpc/powerpc32/power4/strncmp.S: Likewise. * sysdeps/powerpc/powerpc64/power7/strncmp.S: Likewise. * sysdeps/powerpc/powerpc32/power7/strncmp.S: Likewise.
* PowerPC LE strnlenAlan Modra2013-10-043-102/+125
| | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00098.html The existing strnlen code has a number of defects, so this patch is more than just adding little-endian support. The changes here are similar to those for memchr. * sysdeps/powerpc/powerpc64/power7/strnlen.S (strnlen): Add little-endian support. Remove unnecessary "are we done" tests. Handle "s" wrapping around zero and extremely large "size". Correct main loop count. Handle single left-over word from main loop inline rather than by using small_loop. Correct comments. Delete "zero" tail, use "end_max" instead. * sysdeps/powerpc/powerpc32/power7/strnlen.S: Likewise.
* PowerPC LE strlenAlan Modra2013-10-045-47/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00097.html This is the first of nine patches adding little-endian support to the existing optimised string and memory functions. I did spend some time with a power7 simulator looking at cycle by cycle behaviour for memchr, but most of these patches have not been run on cpu simulators to check that we are going as fast as possible. I'm sure PowerPC can do better. However, the little-endian support mostly leaves main loops unchanged, so I'm banking on previous authors having done a good job on big-endian.. As with most code you stare at long enough, I found some improvements for big-endian too. Little-endian support for strlen. Like most of the string functions, I leave the main word or multiple-word loops substantially unchanged, just needing to modify the tail. Removing the branch in the power7 functions is just a tidy. .align produces a branch anyway. Modifying regs in the non-power7 functions is to suit the new little-endian tail. * sysdeps/powerpc/powerpc64/power7/strlen.S (strlen): Add little-endian support. Don't branch over align. * sysdeps/powerpc/powerpc32/power7/strlen.S: Likewise. * sysdeps/powerpc/powerpc64/strlen.S (strlen): Add little-endian support. Rearrange tmp reg use to suit. Comment. * sysdeps/powerpc/powerpc32/strlen.S: Likewise.
* PowerPC SIGSTKSZAlan Modra2013-10-042-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00093.html This copies the sparc version of sigstack.h, which gives powerpc #define MINSIGSTKSZ 4096 #define SIGSTKSZ 16384 Before the VSX changes, struct rt_sigframe size was 1920 plus 128 for __SIGNAL_FRAMESIZE giving ppc64 exactly the default MINSIGSTKSZ of 2048. After VSX, ucontext increased by 256 bytes. Oops, we're over MINSIGSTKSZ, so powerpc has been using the wrong value for quite a while. Add another ucontext for TM and rt_sigframe is now at 3872, giving actual MINSIGSTKSZ of 4000. The glibc testcase that I was looking at was tst-cancel21, which allocates 2*SIGSTKSZ (not because the test is trying to be conservative, but because the test actually has nested signal stack frames). We blew the allocation by 48 bytes when using current mainline gcc to compile glibc (le ppc64). The required stack depth in _dl_lookup_symbol_x from the top of the next signal frame was 10944 bytes. I guess you'd want to add 288 to that, implying an actual SIGSTKSZ of 11232. * sysdeps/unix/sysv/linux/powerpc/bits/sigstack.h: New file.
