Hi,
I'm trying to compile the latest CVS-snapshot (19990615) on my HP 715/33
using gcc 2.7.2.2 and binutils 2.7. Compiling kernel/sched.c gives the
following error:
sched.c:579: section attributes are not supported for this target
I am running HP-UX 10.20, so I cannot use the depots from
ftp://puffin.external.hp.com/pub/parisc/binaries/depot/.
So the question is: do I need gcc 2.8.1 and binutils 2.9.1 to build the
kernel on HP-UX or is this some other error ?

I'm pretty sure you need the hacked egcs and binutils. You can check them
out of cvs from the same place as the kernel (I use them for cross-compiling
though).

gcc 2.8.1 isn't quite enough. Although it does support section
attributes, there is a bug in the code emitted that cannot be assembled
with gas 2.9.1. I sucessfully worked around it by changing the condition
from a fatal error to a warning in gas.
Here is the text of the bug I submitted to gcc:
e of __attribute__((__section__())) to force code into a specific
section
generates code which causes the assembler to fail.
Here is an example:
/* test.c */
int __attribute__ ((__section__ (".text.init"))) a(x)
int x;
{
return(x+1);
}
int b(x)
int x;{
return(x+2);
}
int __attribute__ ((__section__ (".text.init"))) c(x)
int x;{
return(x+1);
}
main(){
printf("a(0)=%d\n",a(0));
printf("b(0)=%d\n",b(0));
printf("c(0)=%d\n",c(0));
}
Here is the output of gcc:
# gcc test.c
/var/tmp/cca10410.s: Assembler messages:
/var/tmp/cca10410.s:59: Warning: Parameters of an existing subspace
can't be modified
/var/tmp/cca10410.s:59: Error: Rest of line ignored. First ignored
character is`,'.
Creating the assembly language output and examining for .SUBSPA
directives, we
find the following:
# gcc -S test.c
# grep SUBSPA test.s
# gcc -S test.c
# grep SUBSPA test.s
.SUBSPA $DATA$,QUAD=1,ALIGN=8,ACCESS=31
.SUBSPA $BSS$,QUAD=1,ALIGN=8,ACCESS=31,ZERO,SORT=82
.SUBSPA $LIT$,QUAD=0,ALIGN=8,ACCESS=44
.SUBSPA $CODE$,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY
.SUBSPA .text.init,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY,SORT=24
.SUBSPA a
.SUBSPA $CODE$
.NSUBSPA $CODE$,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY
.SUBSPA .text.init,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY,SORT=24
.SUBSPA c
.SUBSPA $LIT$
.SUBSPA $CODE$
.NSUBSPA $CODE$,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY
Note that the section .text.init is declared with all the parameters
twice.
The second occurance should not include the parameters.
If the second declaration is edited to remove the parameters, then the
code
assembles and run correctly.
# cp test.s test_fixed.s
# vi test_fixed.s
# diff test.s test_fixed.s
59c59
< .SUBSPA .text.init,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY,SORT=24
---
> .SUBSPA .text.init
# gcc -o test_fixed test_fixed.s
# ./test_fixed
a(0)=1
b(0)=2
c(0)=1

Ulrich,
You can get HP-UX 10.20 binaries at http://hpux.cae.wisc.edu They have
gcc 2.8.1. They also have many other Open Source packages.

I suppose I should mention that the only reason I chose to compile gcc
2.8.1 and binutils 2.9.1 was that I was almost positive that gcc 2.8.1
would build with the bundled K&R compiler. (I couldn't find a copy of
the ANSI C compiler for 11 over the weekend.) I figured that the
vanilla gcc and binutils would give me enough of a development
environment that I could build anything else.
I have binaries of egcs 1.1.2 built, but I'm going to try to run the
test suite before I put them out on puffin.external.hp.com. After
that, I'll go for the CVS versions. When it looks like everything is
built for 11, I'll probably go back and build 10.20 binaries of
anything you can't already find on hpux.cs.utah.edu or
hpux.cae.wisc.edu.
BTW, I've tested the bash binary... It seems to work fine.

I haven't tried your sample but I don't have the the section problem
with gcc-2.95 (prerelease) and binutils-2.9.4 (pre). I do have a
link problem:
