Hi Michael, The tls.pdf (ELF Handling for Thread Local Storage)
#define R_386_TLS_TPOFF 14 /* Negative offset in the static TLS Block */ #define R_386_TLS_TPOFF32 37 /* Offset in TLS Static Block */ However the Solaris uses on R_386_TLS_TPOFF and not R_386_TLS_TPOFF32 in the file elf_386.h.

But I would assume so - yes. Have TLS instruction sequences been defined for the ARM processor? That would answer your question I think. _Mike_ On 2/22/07, Deepak Bhatia <deepak.bhatia at iap-online.com> wrote: > Hi Michael, > > I see that you have written the TLS related stuff for Sparc and i386.
