| The gdtoa code here is based on David M. Gay's original |
| gdtoa source at http://www.netlib.org/fp/ from Jan. 6, |
| 2023. The major changes between the original source and |
| the mingw port here include: |
| |
| * IBM, CRAY and VAX code removed. |
| * KR_headers, ANSI, Void and Char ifdefs are removed. |
| * gdtoa symbols are prepended with "__". |
| * g_xfmt() uses __fpclassifyl() instead of interpreting |
| the flags bit-wise. |
| * lo0bits() and hi0bits() of misc.c replaced by wrappers |
| to gcc's __builtin_clz() |
| * The double/ulong union renamed from U to dbl_union |
| (grep'ped better..) |
| * A few compiler warning fixes here and there. |
| * A few other insignificant changes (if any..) |
| * set_max_gdtoa_threads functionality removed |
| |
| MinGW specific compile-time definitions are at the top of |
| gdtoaimp.h and gdtoa.h headers. |
