| 24 /* In Tru64 UNIX V5.1, Compaq introduced a new assembler | |
| 25 (/usr/lib/cmplrs/cc/adu) which currently (versions between 3.04.29 and | |
| 26 3.04.32) breaks mips-tfile. Passing the undocumented -oldas flag reverts | |
| 27 to using the old assembler (/usr/lib/cmplrs/cc/as[01]). | |
| 28 | |
| 29 The V5.0 and V5.0A assemblers silently ignore -oldas, so it can be | |
| 30 specified here. | |
| 31 | |
| 32 It is clearly not desirable to depend on this undocumented flag, and | |
| 33 Compaq wants -oldas to go away soon, but until they have released a | |
| 34 new adu that works with mips-tfile, this is the only option. | |
| 35 | |
| 36 In some versions of the DTK, the assembler driver invokes ld after | |
| 37 assembly. This has been fixed in current versions, but adding -c | |
| 38 works as expected for all versions. */ | |
