The change implements cexpl() for both ld80 and ld128 architectures. Testing was done on x86_64 and aarch64 systems. Along the way sincos[fl]() use an optimization that reduces the argument to being done one rather than twice. This optimization actually pointed to a bug in the ld128 version of sincosl(), which is now fixed. In addition, the minmax polynomial coefficients for sincosl() have been updated. A concise log of the file-by-file changes follows. * include/complex.h: . Add a prototype for cexpl(). * lib/msun/Makefile: . Add s_cexpl.c to the build. . Setup a link for cexpl.3 to cexp.3. * lib/msun/Symbol.map: . Expose cexpl symbol in libm shared library. * lib/msun/ld128/s_cexpl.c: * Implementation of cexpl() for 128-bit long double architectures. Tested on an aarch64 system. * lib/msun/ld80/s_cexpl.c: * Implementation of cexpl() for Intel 80-bit long double. * lib/msun/man/cexp.3: . Document cexpl(). * lib/msun/man/complex.3: . Add a BUGS section about cpow[fl]. * lib/msun/src/s_cexp.c: . Include float.h for weak references on 53-bit long double targets. . Use sincos() to reduce argument reduction cost. * lib/msun/src/s_cexpf.c: . Use sincosf() to reduce argument reduction cost. * lib/msun/src/k_sincosl.h: . Catch up with the new minmax polynomial coefficients for the kernel for the 128-bit cosl() implementation. . BUG FIX: *cs was used where *sn should have been. This means that sinl() was no computed correctly when iy != 0. * lib/msun/src/s_cosl.c: . Include fpmath.h to get access to IEEEl2bits. . Replace M_PI_4 with pio4, a 64-bit or 113-bit approximation for pi / 4. PR: 216862 MFC after: 1 week |
