Subject: [PATCH] isfinite, isinf, isnan tests: fix for little-endian PowerPC
|
|
|
497cbe |
|
|
|
497cbe |
* tests/test-isfinite.c (test_isfinitel): Only manipulate the
|
|
|
497cbe |
first double of a PowerPC "double double" pair.
|
|
|
497cbe |
* tests/test-isinf.c (test_isinfl): Likewise.
|
|
|
497cbe |
* tests/test-isnan.c (test_long_double): Likewise.
|
|
|
497cbe |
* tests/test-isnanl.h (main): Likewise.
|
|
|
497cbe |
* tests/test-signbit.c (test_signbitl): Likewise.
