| 15 |
|
|---|
| 16 | New features and fixes:
|
|---|
| 17 |
|
|---|
| 18 | o Filehandle rewrite. Files, pipes and sockets now share the same
|
|---|
| 19 | handle space.
|
|---|
| 20 |
|
|---|
| 21 | o Updated binutils from v2.11.2 to v2.14 adding as-elf.exe and
|
|---|
| 22 | ld-elf.exe as goodies for the adventurous.
|
|---|
| 23 |
|
|---|
| 24 | o GCC defines __INNOTEK_LIBC__=0x005.
|
|---|
| 25 | The value reflects the LIBC version, form: 0xGMM
|
|---|
| 26 | Where G=major version and MM=middle version numbers.
|
|---|
| 27 |
|
|---|
| 28 | o Changed library search algorithms for the linkers (emxomfld
|
|---|
| 29 | and ld). Three variations, static, shared and shared+dll.
|
|---|
| 30 | (The options indicated corresponds to what binutils 2.12.x
|
|---|
| 31 | documents.)

|
|---|
| 44 | shared+dll: (-Zdll-search with -Bshared, -call_shared, -dy)
|
|---|
| 45 | 1. libfoo_dll.a
|
|---|
| 46 | 2. foo_dll.a

|---|
| 55 | o Added macros to os2emx.h for preserving FPU control word and
|
|---|
| 56 | applied these to certing read and write operations in LIBC.
|
|---|
| 57 |
|
|---|
| 58 | o Added feature to emxomfld to automatically convert a.out
|
|---|
