* NEWS: Describe patch. * bootstrap.conf (gnulib_modules): Add ftoastr. * src/od.c: Include ftoastr.h, not float.h. (FLT_DIG, DBL_DIG): Remove. No need to verify LDBL_DIG. (FMT_BYTES_ALLOCATED): No need to worry about floating point now, since this format is no longer used for floating point. (PRINT_FIELDS): New macro, with most of the guts of the old PRINT_TYPE. (PRINT_TYPE): Rewrite to use PRINT_FIELDS. (PRINT_FLOATTYPE): New macro. This uses the new functions from ftoastr. (print_float, print_double, print_long_double): Reimplement using PRINT_FLOATTYPE. (decode_one_format): Calculate field widths based on ftoastr-supplied macros. * tests/Makefile.am (TESTS): Add misc/od-float. * tests/misc/od-float: New file.

# Test for a bug in coreutils up through 8.7: od was losing
|
|
# information when asked to parse floating-point values. The numeric
|
|
# tests are valid only on Intel-like hosts, but that should be good
|
|
# enough to detect regressions, as they are designed to succeed on
|
|
# non-Intel-like hosts. Also, test for another bug in coreutils 8.7
|
|
# on x86: sometimes there was no space between the columns.
