* Implement _div64 and _mod64 for ppc32Anton Vorontsov2009-12-011-3/+39
| | | | | | | _div64 and _mod64 arch-specific details were taken from gcc/longlong.h, just as it was done for i386. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>
* PR10632: simplify randint() implementationFrank Ch. Eigler2009-09-231-24/+10
| | | | | | | | | * tapset/random.stp (randint): Make it 1-arity (imply min=0). Document with kerneldoc. * doc/Systemtap_Tapset_Reference/tapsets.tmpl: Extract the docs. * runtime/arith.c (_stp_random_pm_u): Rename without _pm. (_stp_random_pm): Rewrite in terms of ..._u. * testsuite/random.stp: Adapt & simplify.
* PR1062: runtime functionCharley Wang2009-09-231-0/+22
| | | | * arith.c (_stp_random_pm_u): New function.
* Use 'static' as much as possibleJosh Stone2009-01-281-11/+11
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.

| | | | | | | | | | | | Patch from Quentin Barnes. * arith.c: Add arm support for 64-bit division. * copy.c: Enable arm support. * loc2c-runtime.h: Ditto. * regs.[ch]: Ditto. * stack.c: Include stack-arm.c. * stack-arm.c: New file. * time.c (_stp_gettimeofday_ns): hack for arm. See PR 4569.

| | | | | | | * arith.c (_stp_div64): Check for division by 0 or -1 first. This simplifies things and removes the possibility of x86_64 trying LLONG_MIN/-1 and faulting. (_stp_mod64): Ditto.

| | | | | | | | * stat-common.c (_stp_stat_print_valtype): Use _stp_div64(). * arith.c (_stp_div64): Check error before writing to it. Remove check against 32-bit LONG_MIN and -1. That only applies to 64-bit. (_stp_mod64): Ditto.
* 2005-09-08 Martin Hunt <hunt@redhat.com>hunt2005-09-081-4/+5
| | | | | * arith.c (_stp_div64): Check for overflow. (_stp_mod64): Ditto.
* 2005-09-08 Martin Hunt <hunt@redhat.com>hunt2005-09-081-63/+275
| | | | | | | | * arith.c (_stp_div64): For 64-bit cpus, just use native division. Otherwise call _div64(). (_stp_mod64): Call _mod64() isf necessary. (_div64): 64-bit division for 32-bit cpus. (_mod64): 64-bit modulo for 32-bit cpus.
