Re: [PATCH][M68K] Binutils support for TLS
FWIW, just interested, having done most of the TLS
implementation for CRIS recently.

There's room for confusion here. For the TLS offset itself, yes
that's where you typically put it, but I was referring to the
relocation to get to that GOT entry. Looks like there's no
absolute TLS-IE-specific relocation into the GOT, just a
GOT-relative one. Ok, confirmed by the GCC patches, never mind.
(I almost did that for CRIS recently, see recent
R_CRIS_32_IE-patch.)
brgds, H-P
PS. typical TLS module size being in the order of 100 bytes,
I found there's no need to optimize for 16-bit accesses with
offsets and such. :)
