...for profiling require the use of a target library, a complete backend. It is very sad, that they have discontinued their MIPS backend years ago, and only Alpha, and backends for the ugly x86. In terms of research, the most necessary backends are the following (personal opinion). 1. MIPS R3000, R4400, R10000 2. SPARC V7 to V9 (very close to no. 1) 3. PowerPC 4. ARM7, ARM9, ARM11 5. Alphas, but since the Alpha has very low sales in Europe, and talking from my point of view it is not that necessary. If a backend is to be used you have to do at least the following: do_gen ... with option -target...

I should be able to check R4400 (that is virtually the same as R4000) next week or so. As to SiByte -- not before next month I'm afraid. I don't have access to any of the other processors you named.

Hi, since I switched from SSH 1 to OpenSSH 2.9p2/2.9.9p2/3.0p1 Snapshot I suffer from awfully slow connection performance. Once the connection is established, performance is perfectly ok.
