[PATCH] Support more sparc relocs

David Miller davem@davemloft.net
Sat Apr 7 14:46:00 GMT 2012


This adds support for R_SPARC_H34 and R_SPARC_WDISP10.

R_SPARC_H34 is used for a 34-bit absolute code model,
basically accesses look like this:

	sethi	%h34(symbol), %g1
	sllx	%g1, 2, %g1
	or	%g1, %l34(symbol), %g1

or:

	sethi	%h34(symbol), %g1
	sllx	%g1, 2, %g1
	ld	[%g1 + %l34(symbol)], %g1

Note that an explicit R_SPARC_L34 was not created, we simply use
R_SPARC_L44 since that makes the calculate we want.  I've added
entries to sparc's reloc64 test case to cover this.

R_SPARC_WDISP10 will be used in support for newer instructions in an
upcoming set of changes.  I'll add test cases for this relocation
when I add those instructions.

You may notice that I added the R_SPARC_32/R_SPARC_64 entries to the
sparc BFD howto table.  This was to simplify the indexing of
R_SPARC_H34 and R_SPARC_WDISP10.  If I didn't add the
R_SPARC_32/R_SPARC_64 entries I'd have to add seperate howto objects
outside of the array which would be ugly and really not necessary.

I plan to add proper R_SPARC_32 and R_SPARC_64 support some time
soon.

Ok to commit?
