[BZ #6810]
|
||||
* math/w_tgamma.c: Include <errno.h>.
|
||||
(__tgamma): Use __glibc_unlikely. Set errno on underflow to 0.
|
||||
* math/w_tgammaf.c: Include <errno.h>.
|
||||
(__tgammaf): Use __glibc_unlikely. Set errno on underflow to 0.
|
||||
* math/w_tgammal.c: Include <errno.h>.
|
||||
(__tgammal): Use __glibc_unlikely. Set errno on underflow to 0.
|
||||
* math/auto-libm-test-in: Do not allow missing errno on tgamma
|
||||
underflow. Add more tgamma tests.
|
||||
* math/auto-libm-test-out: Regenerated.
|
||||
* sysdeps/i386/fpu/libm-test-ulps: Update.
|
||||
* sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
|
||||
|
||||
* math/auto-libm-test-in: Add tests of log, log10, log1p, log2,
|
||||
sin, sinh, tan, tanh, tgamma, y0 and y1.
|
||||
* math/auto-libm-test-out: Regenerated.
