 181         using -O1 and adding more explicit -O2 optimizations, just so we

 288         Make CYGPKG_LIBM_COMPATIBILITY_DEFAULT require CYGPKG_LIBC
 289         rather than all of libm, and put a check (with #error) that
 290         this is the case
 291
 292         * src/double/ieee754-api/w_scalb.c:
 293         Only include errno.h if we aren't IEEE-only
 294
 295         * src/double/portable-api/s_ldexp.c, src/misc/standard.c:
 296         Make the error checking in s_ldexp.c more like every other libm

 299
 300         * tests/vectors/acos.c, tests/vectors/asin.c,
 301           tests/vectors/atan.c, tests/vectors/atan2.c,

 308           tests/vectors/sinh.c, tests/vectors/sqrt.c, tests/vectors/tan.c,
 309           tests/vectors/tanh.c:
 310         Remove unnecessary include of <errno.h>
 311
 312         * tests/vectors/vector_support.h:
 313         Only include errno.h if we aren't IEEE-only.
 314         If we don't have Cyg_ErrNo, just use a cyg_int32 instead, to
 315         make sure that the fields are still correct for the input
 316         test vector.
 317         In doTestVec(), before checking errno, check if we're
 318         in IEEE mode (either compiled in or set at runtime) because if
 319         so, and errno is set in the errno field of the input test
 320         vector, then we have to skip this, since we can't validate the
 321         output.
 322         In all modes, if errno is set in the input test vector, don't
 323         bother checking the actual values
 324
 325         All of the above changes are for PR 17503
 326
 327         * tests/vectors/pow.c:
 328         Remove requirement of being in POSIX mode, as the change to
 329         vector_support.h should make this work better now.
 330
 331
 332 Sun Sep 27 20:46:09 1998  David Moore  <dsm@keema.cygnus.co.uk>
 333

 336
 337 1998-09-26  Bart Veer  <bartv@cygnus.co.uk>
 338
 339         * include/pkgconf/libm.h:
 340         PR 17503: there are uses of errno in a couple of places in libm,
 341         and errno will only be available if the C library is present.
 342         Therefore libm requires libc.

 350
 351         * src/misc/signgam.cxx:
 352         Make sure CYGNUM_LIBM_SIGNGAM_TRACE_LEVEL is defined before

 354         Fix for PR 17478
 355
 356         * include/pkgconf/libm.h:
 357         Define trace levels only if parent CYGPKG_LIBM_TRACE is defined
 358         for consistency with Configuration Tool
 359
 360 Fri Sep 25 18:25:02 1998  Jonathan Larmour  <jlarmour@cygnus.co.uk>
 361

 371         * src/double/ieee754-api/w_scalb.c:
 372         Use CYGFUN_LIBM_SVID3_scalb for whether 2nd arg of scalb is
 373         double or int, rather than _SCALB_INT.
 374         Fix for PR 17479
 375
 376 Wed Sep 23 08:07:48 1998  Jonathan Larmour  <jlarmour@cygnus.co.uk>
 377
 378         * tests/vectors/pow.c (test):
 379         Make pow test conditional on being in POSIX compatibility mode.
 380         This is the only mode that can set errno correctly, in
 381         relation to what the tests expect.
 382         Fix for PR 16933
 383
