|

* stdlib/gen-tst-strtod-round.c: Add backslash to
|
||||
compile command in comment.
|
||||
(printfp): Remove the literal suffix, and define an infinite
|
||||
value as INF to avoid expansion clash with INFINITY.
|
||||
(round_str): Remove the literal suffix.
|
||||
(round_for_all): Likewise, remove the now duplicate ldbl-64
|
||||
entry, and remove some magic constants.
|
||||
|
||||
* stdlib/tst-strtod-round.c: (TEST): Redefine to reduce
|
||||
duplication. Remove duplicate dbl-64 and ldbl-64 entries.
|
||||
(ROUNDING_TESTS_long_double): Define as 0 for ibm128.
|
||||
(_CONCAT): New macro.
|
||||
(CONCAT): Likewise.
|
||||
(CHOOSE_ld): Likewise.
|
||||
(CHOOSE_f): Likewise.
|
||||
(CHOOSE_d): Likewise.
|
||||
(FTYPE_MEMBER): Likewise.
|
||||
(BOOL_MEMBER): Likewise.
|
||||
(STRUCT_FOREACH_FLOAT_FTYPE): Likewise.
|
||||
(STRUCT_FOREACH_FLOAT_BOOL): Likewise.
|
||||
(_XNTRY): Likewise.
|
||||
(XNTRY): Likewise.
|
||||
(_ENTRY): Likewise.
|
||||
(ENTRY): Likewise.
|
||||
(test_exactness): Generate members via macro.
|
||||
(test_results): Likewise.
|
||||
(test): Update members.
|
||||
(TEST): Redefine using new macros.
|
||||
(INF): New macro.
|
||||
(fetestmodes): New structure.
|
||||
(do_test): Refactor to be type generic.
|
||||
(test_in_one_mode): Refactor duplicate code into
|
||||
(GEN_ONE_TEST): New macro.
|
||||
|
||||
* stdlib/tst-strtod-round-data.h: Regenerate.
|
||||
|
||||
* stdlib/tst-strtod.h (GEN_TEST_STRTOD_FOREACH):
|
||||
Extend to pass additional arbitrary parameters to
|
||||
generators.
