---|
229 | |
---|
230 | *** Major changes in newlib version 1.8.1: |
---|
231 | |
---|
232 | * Added check for --enable-newlib-mb configure option which defines the |
---|
233 | MB_CAPABLE macro. Multibyte support for JIS, SJIS, and EUC-JP implemented. |
---|
234 | |
---|
235 | * Reduced code size for libm modules. |
---|
236 | |
---|

---|
238 | |
---|
239 | *** Major changes in newlib version 1.8.0: |
---|
240 | |
---|
241 | * Added simulated signal handling functions _raise_r, _signal_r, raise, and |
---|
242 | signal except for sparc-sun-sunos*, i[3456]86-*-sco*, and a29k-*-* systems, |
---|
243 | which already provide access to signal. The signal functionality provided |
---|
244 | does not interact with hardware generated signals. |
---|
245 | |
---|
246 | * Added reentrant function rand_r from POSIX.1c. |
---|
247 | |
---|
248 | * Removed _asctime, _next, _scanpoint, and _signgam fields from struct |
---|
249 | _reent. These are no longer necessary since there are now functions |
---|
250 | that explictly support multiple threads (asctime_r, ctime_r, gamma_r, |
---|
251 | gmtime_r, lgamma_r, localtime_r, rand_r, & strtok_r). |
---|
252 | |
---|
253 | |
---|
254 | *** Major changes in newlib version 1.7.0: |
---|
255 | |
---|
256 | * Cross compiler target libraries are now built in a subdir of the top level |
---|
257 | build directory. |
---|
258 | |
---|
259 | Old way: build |
---|
260 | /newlib |
---|
261 | /m68020 |
---|
262 | /m68881 |
---|
263 | New way: |
---|
264 | build |
---|
265 | /m68k-coff |
---|
266 | /m68020 |
---|
267 | /m68881 |
---|
268 | |
---|
269 | where m68020 and m68881 are multilib subdirectories |
---|
270 | |
---|
271 | * m68k targets support --disable options to avoid building unwanted versions |
---|
272 | of the libraries. |
---|
273 | |
---|
274 | --disable-softfloat - don't build libc, libg++, etc. for -msoft-float |
---|
275 | --disable-m68881 - don't build libc, libg++, etc. for -m68881 |
---|
276 | --disable-m68000 - don't build libc, libg++, etc. for -m68000 |
---|
277 | --disable-m68020 - don't build libc, libg++, etc. for -m68020 |
---|
278 | |
---|
279 | These options have *no* effect on the default libraries, so if the default |
---|
280 | is -m68020, --disable-m68020 is nilpotent. |
---|
281 | |
---|
282 | * Reentrancy support in libm removed. |
---|
283 | |
---|
284 | * strtok, strtol, strtoul, assert, div, ldiv, qsort, vfprintf |
---|
285 | replaced with NetBSD versions. |
---|
286 | |
---|
287 | * Support for systems with 32 bit "doubles" added. |
---|
288 | |
---|
289 | * unctrl added. |
---|
290 | |
---|
291 | * dtoa.c updated from master dtoa.c soruces (netlib.att.com) |
---|
292 | |
---|
293 | * Various bug fixes. |
---|
294 | |
---|
295 | *** Major changes in newlib version 1.6.1: |
---|
296 | |
---|
297 | * Added reentrant functions (asctime_r, ctime_r, gmtime_r, localtime_r, |
---|
298 | and strtok_r) from POSIX.1c. |
---|
299 | |
---|
300 | * Removed _asctime_r and _strtok_r functions. |
---|
