>Description:
I'm using an Ultra 1 sparc64 machine for some 32-bit sparc work
(inferno-os, self, etc) using cc -m32 - diskless krups is waaay too
slow for that :)
Unfortunately, native sparc64 gdb cannot handle 32-bit binaries (which
is a separate problem), so I thought I can bring over 32-bit gdb
binary from sparc. Unfortunately^2, that doesn't work:
$ gdb32 -q --args ./NetBSD/sparc/bin/emu -c5 /catchme.dis
Reading symbols from ./NetBSD/sparc/bin/emu...
gdb32: Undefined PLT symbol "__atomic_compare_exchange_1" (symnum = 322)
>How-To-Repeat:
Copy gdb from a sparc (32-bit) build. Try to run it on sparc64:
$ LD_BIND_NOW=1 gdb32
gdb32: Undefined PLT symbol "__sync_bool_compare_and_swap_4" (symnum = 152)
This is on a slightly out of date current:
$ ll distrib/sparc/lib/libc.so.12.222 distrib/sparc64/lib/libc.so.12.222
-r--r--r-- 1 uwe uwe 2228224 Nov 30 15:15 distrib/sparc/lib/libc.so.12.222
-r--r--r-- 1 uwe uwe 2564624 Nov 30 18:01 distrib/sparc64/lib/libc.so.12.222
Some symbols are missing from the 32-bit libc built as part of sparc64
build, compared to the 32-bit libc built as part of the normal sparc
build:
$ nm -D distrib/sparc/lib/libc.so.12.222 | grep atomic_compare
000edc9c T __atomic_compare_exchange_1
00089ba0 T __atomic_compare_exchange_2
000f6490 T __atomic_compare_exchange_4
$ nm -D distrib/sparc64/lib/libc.so.12.222 | grep atomic_compare

src/common/lib/libc/arch/sparc/atomic/Makefile.inc is a crazy mudball
that is included by four different libraries and drags in different
functions depending on which library it's a part of.
I figure the top level .if/.else that tests for sparc64 should really
be just an .if, with most of the file, that is currently inside
sparc's .else, processed unconditionally, so that sparc64 compat32
version gets all the symbols that sparc also gets.
