path: root/SHARED-FILES

# Files shared with other projects.  Pass a file path to the
# get_glibc_shared_code() function in the python library
# scripts/glibc_shared_code.py to get a dict object with this information.  See
# the library sources for more information.

# The headers on most of these files indicate that glibc is the canonical
# source for these files, although in many cases there seem to be useful
# changes in the gnulib versions that could be merged back in. Not all gnulib
# files contain such a header and it is not always consistent in its format, so
# it would be useful to make sure that all gnulib files that are using glibc as
# upstream have a greppable header.
#
# These files are quite hard to find without a header to grep for and each file
# has to be compared manually so this list is likely incomplete or may contain
# errors.

  (file src/binary32/tgamma/tgammaf.c in CORE-MATH)
  Instructions to merge new versions:
  - change the function name from cr_tgammaf to __ieee754_gammaf_r
  - add "int *signgamp" as 2nd argument and add at the beginning:
    if (signgamp != NULL) *signgamp = 1;
  - remove the errno stuff (this is done by the wrapper)
  - replace 0x1p127f * 0x1p127f by math_narrow_eval (x * 0x1p127f)
  - replace 0x1p-127f * sgn[k&1] by math_narrow_eval (0x1p-127f * sgn[k&1])
  - add libm_alias_finite (__ieee754_gammaf_r, __gammaf_r) at the end
