|---|

|---|
| 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. |
|---|
