*** Major changes in newlib version 1.9.0:
* i[3456]86-pc-linux support
* Long Double I/O support via the WANT_IO_LONG_DBL flag
* addition of reentrant environment functions
* addition of xscale and AVR platforms
* severe reduction in the number of warnings issued
* consolidation of many RTEMS features into shared headers
2000-02-18 03:39:52 +08:00
*** Major changes in newlib version 1.8.2:
* RTEMS features and fixes from Joel Sherrill.
* More work on reentrant routines.
* 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.
* Reduced code size for libm modules.
* Replaced the BSD malloc with Doug Lea's malloc.
*** 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.
