/* In Tru64 UNIX V5.1, Compaq introduced a new assembler
|
| 26 |
|
|
(/usr/lib/cmplrs/cc/adu) which currently (versions between 3.04.29 and
|
| 27 |
|
|
3.04.32) breaks mips-tfile. Passing the undocumented -oldas flag reverts
|
| 28 |
|
|
to using the old assembler (/usr/lib/cmplrs/cc/as[01]).
|
| 29 |
|
|
|
| 30 |
|
|
The V5.0 and V5.0A assemblers silently ignore -oldas, so it can be
|
| 31 |
|
|
specified here.
|
| 32 |
|
|
|
| 33 |
|
|
It is clearly not desirable to depend on this undocumented flag, and
|
| 34 |
|
|
Compaq wants -oldas to go away soon, but until they have released a
|
| 35 |
|
|
new adu that works with mips-tfile, this is the only option.
|
| 36 |
|
|
|
| 37 |
|
|
In some versions of the DTK, the assembler driver invokes ld after
|
| 38 |
|
|
assembly. This has been fixed in current versions, but adding -c
|
| 39 |
|
|
works as expected for all versions. */
