Hi,
Uli pointed out to me that now SH TLS ABI doesn't need R_SH_TLS_*_MOV
relocations. I've fixed binutils and then found the current macros
for SH in elf/tls-macros.h don't match ABI. Here is a fix.
BTW, I've revised my tiny TLS memo
<URL:http://dodo.nurs.or.jp/~kkojima/gnu-on-sh/tls-sh-memo.txt>.
I'll send binutils changes to binutils mailing list ASAP.
Regards,
kaz
