[PATCH 2/3] newlib: Add non LDBL_EQ_DBL math support for aarch64, i386, and x86_64
Jennifer Averett
jennifer.averett@oarcorp.com
Mon Apr 3 20:58:36 GMT 2023
Rename s_nearbyint.c to remove conflicts
Remove functions that are not needed from s_nearbyint.c
Modify include paths
Add missing types
Create Makefiles
Create header files to resolve dependencies between directories
Modify some instances of unsigned long to uint64_t for 32 bit platforms
Add HAVE_FPMATH_H
