1 | If you use the 1.31 version of the MIPS assembler (such as was shipped |
2 | with Ultrix 3.1), you will need to use the -fno-delayed-branch switch | |
3 | when optimizing floating point code. Otherwise, the assembler will | |
4 | complain when the GCC compiler fills a branch delay slot with a | |
5 | floating point instruction, such as add.d. | |
6 | ||
7 | The GCC compiler on the MIPS will put small strings into the short | |
8 | data area, rather than the read-only data section. This is so that | |
9 | references to the strings only take one instruction, instead of the | |
10 | normal two instructions. | |

12 | Users have reported some problems with version 2.0 of the MIPS | |
13 | compiler tools (Ultrix 4.1). Version 2.10 seems to work (Ultrix 4.2). |
