Hello,
Just put together a rudimentary patch to add support for Linux running on HP's PA-Risc
(HPPA) processors.
1. The only test I have is the one embedded in the Makefile; if there are more
strenuous tests,
please point me to them.
2. The PA-Risc architecture has both 32- and 64-bit processors. Both are supported by
Linux, although the
userland toys are lagging behind on the 64-bit binaries. My point here is,
a. I have a 32-bit processor, with gcc 3.0.2 configured for 32-bit binaries,
as per distributed with Debian "pre-" woody. If a user has their compiler
configured for 64-bit emission, I don't anything in the patch to detect that,
and set your #define for 64-bit longs (SIXTY_FOUR_BIT_LONG)
b. Even if a 64-bit processor, I don't have code to throttle the compiler back to
32-bit
mode, and unset the 64-bit long #define.
3. There's some questions regarding instruction scheduling to use with some of the
processors. I
document the connidrum in ./config, in case someone else has better information, or
gcc changes
it's -mschedule=xx -march=xx flags at some time in the future.
4. Manifest
a. Linux 2.4.16-pa24
b. Glibc 2.2.4
c. Gcc 3.0.2
d. Binutils 2.11.92.0.12.3
