Define segments for Thread Local Storage.
Here's what the elf tls spec says:
Field .tbss .tdata
sh_name .tbss .tdata
sh_type SHT_NOBITS SHT_PROGBITS
sh_flags SHF_ALLOC|SHF_WRITE| SHF_ALLOC|SHF_WRITE|
SHF_TLS SHF_TLS
sh_addr virtual addr of section virtual addr of section
sh_offset 0 file offset of initialization image
sh_size size of section size of section
sh_link SHN_UNDEF SHN_UNDEF
sh_info 0 0
sh_addralign alignment of section alignment of section
sh_entsize 0 0
We want _tlsstart and _tlsend to bracket all the D tls data.
The default linker script (ld -verbose) says:
.tdata : { *(.tdata .tdata.* .gnu.linkonce.td.*) }
.tbss : { *(.tbss .tbss.* .gnu.linkonce.tb.*) *(.tcommon) }
so if we assign names:
_tlsstart .tdata
symbols .tdata.
symbols .tbss
_tlsend .tbss.
this should work.
Don't care about sections emitted by other languages, as we presume they
won't be storing D gc roots in their tls.
Output:
seg_tlsseg set to segment number for TLS segment.
