If i change the test case for the Sun assembler:

__kmp_unnamed_critical_addr:
    .xword .gomp_critical_user_ + 0x1234567890

i get this:

address@hidden/builds/steleman/userland-s12-binutils-gas-24380705/components/binutils/build/sparcv9/gas][08/02/2016
7:30:35][544]>> /usr/bin/as -m32 -xarch=v8plusa test32-sun.S -o test32-sun.o
/usr/bin/as: "test32-sun.S", line 14: warning: value does not fit in 32 bits
address@hidden/builds/steleman/userland-s12-binutils-gas-24380705/components/binutils/build/sparcv9/gas][08/02/2016
7:30:43][545]>> readelf -sW --relocs test32-sun.o 

Relocation section '.rela.data' at offset 0xf8 contains 1 entries:
 Offset     Info    Type                Sym. Value  Symbol's Name + Addend
00000004  00000303 R_SPARC_32             00000008   .gomp_critical_user_ +
34567890

Symbol table '.symtab' contains 5 entries:
   Num:    Value  Size Type    Bind   Vis      Ndx Name
     0: 00000000     0 NOTYPE  LOCAL  DEFAULT  UND 
     1: 00000000     0 FILE    LOCAL  DEFAULT  ABS test32-sun.S
     2: 00000000     0 SECTION LOCAL  DEFAULT    2 
     3: 00000008    64 OBJECT  GLOBAL DEFAULT  COM .gomp_critical_user_
     4: 00000000     8 OBJECT  GLOBAL DEFAULT    2 __kmp_unnamed_critical_addr

Same as GAS, but the Sun assembler emits a warning.

Which now creates a new and interesting question that i am going to run
by the Solaris linker people: isn't this a Solaris rtld bug, in final
analysis?

I will ask the linker folks and i will come up with more test cases
for the other relocations.

Thank you very much!
