|
|
|

|
|
|
|
* Floating point math library check, --enable-newlib-hw-fp.
|
|
|
|
*** Major changes in newlib version 1.8.1:
|
|
|
|
* Added check for --enable-newlib-mb configure option which defines the
|
|
MB_CAPABLE macro. Multibyte support for JIS, SJIS, and EUC-JP implemented.

|
|
*** Major changes in newlib version 1.8.0:
|
|
|
|
* Added simulated signal handling functions _raise_r, _signal_r, raise, and
|
|
signal except for sparc-sun-sunos*, i[3456]86-*-sco*, and a29k-*-* systems,
|
|
which already provide access to signal. The signal functionality provided
|
|
does not interact with hardware generated signals.
|
|
|
|
* Added reentrant function rand_r from POSIX.1c.
|
|
|
|
* Removed _asctime, _next, _scanpoint, and _signgam fields from struct
|
|
_reent. These are no longer necessary since there are now functions
|
|
that explictly support multiple threads (asctime_r, ctime_r, gamma_r,
|
|
gmtime_r, lgamma_r, localtime_r, rand_r, & strtok_r).
|
|
|
|
|
|
*** Major changes in newlib version 1.7.0:
|
|
|
|
* Cross compiler target libraries are now built in a subdir of the top level
|
|
build directory.
|
|
|
|
Old way: build
|
|
/newlib
|
|
/m68020
|
|
/m68881
|
|
New way:
|
|
build
|
|
/m68k-coff
|
|
/m68020
|
|
/m68881
|
|
|
|
where m68020 and m68881 are multilib subdirectories
|
|
|
|
* m68k targets support --disable options to avoid building unwanted versions
|
|
of the libraries.
|
|
|
|
--disable-softfloat - don't build libc, libg++, etc. for -msoft-float
|
|
--disable-m68881 - don't build libc, libg++, etc. for -m68881
|
|
--disable-m68000 - don't build libc, libg++, etc. for -m68000
|
|
--disable-m68020 - don't build libc, libg++, etc. for -m68020
|
|
|
|
These options have *no* effect on the default libraries, so if the default
|
|
is -m68020, --disable-m68020 is nilpotent.
|
|
|
|
* Reentrancy support in libm removed.
|
|
|
|
* strtok, strtol, strtoul, assert, div, ldiv, qsort, vfprintf
|
|
replaced with NetBSD versions.
|
|
|
|
* Support for systems with 32 bit "doubles" added.
|
|
|
|
* unctrl added.
|
|
|
|
* dtoa.c updated from master dtoa.c soruces (netlib.att.com)
|
|
|
|
* Various bug fixes.
|
|
|
|
*** Major changes in newlib version 1.6.1:
|
|
|
|
* Added reentrant functions (asctime_r, ctime_r, gmtime_r, localtime_r,
|
|
and strtok_r) from POSIX.1c.
|
|
|
|
* Removed _asctime_r and _strtok_r functions.
