[PATCH]: Add sparc gotdata reloc infrastructure.
- From: David Miller <davem at davemloft dot net>
- To: binutils at sourceware dot org
- Date: Sat, 12 Apr 2008 23:22:47 -0700 (PDT)
- Subject: [PATCH]: Add sparc gotdata reloc infrastructure.
This adds enough infrastructure for binutils to support gotdata
relocations on Sparc. It doesn't yet, however, add code to perform
the code optimizations possible using these relocations. I will add
those later as a follow-on patch.
Basically the idea with these things is that the compiler can emit
(assuming %l7 == &_GLOBAL_OFFSET_TABLE_[0]):
sethi %gdop_hix22(symbol), %reg1
xor %reg1, %gdop_lox10(symbol), %reg1
ld [%l7 + %reg1], %reg2, %gdop(symbol)
Those three instruction will cause the assembler to generate
relocations R_SPARC_GOTDATA_OP_HIX22, R_SPARC_GOTDATA_OP_LOX10, and
R_SPARC_GOTDATA_OP respectively.
When the linker sees this, and it knows that the symbol in the final
object is within +/- 2GB of _GLOBAL_OFFSET_TABLE_ and it knows the
final relative offset, it can transform the above into:
sethi %hix22(symbol - _GLOBAL_OFFSET_TABLE_), %reg1
xor %reg1, %lox10(symbol - _GLOBAL_OFFSET_TABLE_), %reg1
add %l7, %reg1, %reg2
For now, however, the BFD linker simply leaves this as a normal full
unoptimized GOT sequence.
I plan next to add support to GCC so that it can emit the above
sequences. I will also add similar unoptimized, and eventual
optimized, support for gotdata relocs into my gold sparc target.
Regression tested on sparc{,64}-unknown-linux-gnu

Simply ignore R_SPARC_GOTDATA_OP relocations.
