This patch adds a new target, c6x-uclinux, to the TI C6X port. This uses
a new kind of binary format called DSBT ELF, designed to support shared
libraries on nommu systems. Every object (shared libraries, executables,
dynamic linker) has an index, and a table at the start of the GOT to
provide data segment pointers. The mechanism is similar to the ID
shared-flat format which is used on m68k or Blackfin, but using real ELF
binaries instead of flat ones.
Also included in this patch is support for a new assembler directive,
".scomm", used to better support small-data common symbols as required
by the ABI. There's also a small assembler bugfix for -mgenerate-rel.
This patch does not yet include C++ EH support; I expect Paul Brook will
submit those parts a bit later.

There's also a small assembler bugfix for -mgenerate-rel. Why exactly is a .scommon section needed in addition to .bss and .far - how does it differ from those two sections? Also, this directive appears to generate SHN_TIC6X_SCOMMON in object files. I don't see any sign of this in the ABI ("There are no processor-specific special section indexes defined.") - exactly what specification of it has been agreed with TI? We can't put processor-specific section indices in object files unless they are defined by the ABI (including having a specification agreed for the next ABI version). I also notice that the diagnostics in .scomm parsing often fail to follow the GNU Coding Standards (other diagnostics in tc-tic6x.c make sure to avoid initial capital letters or trailing '.'; they also avoid the grave accent as an opening quote, although this last style point, though consistent with GCC, is outside the GNU Coding Standards). In addition, .scomm handling should have assembler testcases for both correct and invalid uses (covering the different diagnostics). I haven't yet reviewed the whole patch, but some other comments and questions: * There is a reference to R_386_COPY in the patch, which is clearly wrong. * R_C6000_SBR_GOT32, added to include/elf/tic6x.h by the patch, is not the name agreed for the next version of the ABI; that's R_C6000_EHTYPE. * I presume semantics for R_C6000_EHTYPE, R_C6000_PCR_H16, and R_C6000_PCR_L16 are to be added in subsequent patches, since only the definitions and nothing else are added in this patch. (HOWTO entries for new relocations are useful even without more substantive linker support, since they are used by objdump when processing objects - maybe produced with the TI tools - that contain the relocations.) * I think the static functions in elf32-tic6x.c should be consistently named with an elf32_tic6x_ prefix (e.g. using_dsbt, install_rela, make_got_dynreloc). * What is the purpose of the ELF_MAXPAGESIZE change (and the logic behind the choice of the new value)? I don't think the value is of much significance, but it would be good to know why the change was needed. * There is a reference to a symbol "__DYNAMIC", which I think should be "_DYNAMIC". (bfin has a reference to "__DYNAMIC", but I think that's because it deviates from the gABI in having a leading underscore on symbol names, unlike C6X.) * Why does elf32_tic6x_gc_sweep_hook handle R_C6000_SBR_GOT_U15_W differently from R_C6000_SBR_GOT_L16_W and R_C6000_SBR_GOT_H16_W?

I'm happy with the directive, and given your other comments with the section index (though it appears there must have been an omission to put this index into the latest ABI version, which postdates the discussion you mention).

Where exactly? There are undefined weak symbols for the ABS32 case (only, as far as I can see) but I can't find which dumps are verifying the resolution to 0 by the static linker (when it's not possible for the symbol to get defined at dynamic link time). -- Joseph S.

I'm generally concerned that I don't understand why there are three sections rather than two here. Why isn't .bss being given this property and used in place of .scommon? Does it break anything for .bss not to have this property - or do .bss and .far already have it? Or, alternatively, if you need both .scommon and .bss, why isn't a separate common section parallel to .far needed, so you would have four sections? It's not clear to me that a new section name was part of the added ABI for small commons (in general dependence on section names is a bit unfortunate, though in the absence of any better ELF way to mark small *data* sections as such I don't see how to avoid it here). -- Joseph S.

What is the far analogue of .scommon? .far : { *(.dynfar) *(.far .far.* .gnu.linkonce.b.*) *(COMMON) <----------- This, I'd think. Certainly if you remove that, far common symbols are dropped. As far as I can tell .scommon (and its far analogue) exists only internally in the linker, but it needs to be given some name to be placed in the right output section (.sbss). The linker documentation explicitly mentions that some targets use a .scommon section. From that, and looking at elf.sc, SBSS=".${SBSS_NAME} ${RELOCATING-0} : { ${RELOCATING+${SBSS_START_SYMBOLS}} ${CREATE_SHLIB+*(.${SBSS_NAME}2 .${SBSS_NAME}2.* .gnu.linkonce.sb2.*)} *(.dyn${SBSS_NAME}) *(.${SBSS_NAME}${RELOCATING+ .${SBSS_NAME}.* .gnu.linkonce.sb.*}) *(.scommon) ${RELOCATING+${SBSS_END_SYMBOLS}} }" as well as a grep for ".scommon" in bfd/, I get the strong impression that's simply how it's meant to work. > Your > patch doesn't change this comment explaining the sections, and I see no > sign of any existing .common section name support for any target, or any > reason why no far analogue would be needed. The far analogue is already handled by the linker (which knows how to deal with _one_ common section), apparently in a somewhat "magical" way. I don't see a reason to change the comment since it documents output sections only, not all of the gazillion possible input section names. > elf32-ppc.c:ppc_elf_add_symbol_hook sets SEC_IS_COMMON on .sbss. .sbss > for that target corresponds to .bss for C6X, as far as the linker scripts > are concerned - what goes wrong with that correspondence to require > another section (but only one other section, not two)? Trying that (naively replacing .scommon with .bss everywhere in elf32-tic6x.c), I get .scomm symbols apparently being placed in .far (in all the shlib linker tests). One immediately obvious problem is that there's no longer anything reasonable for elf32_tic6x_section_from_bfd_section to do. I don't know any of the PPC ABIs, and I haven't investigated any further; we have a mechanism that works, and works the same way as other targets.

Thanks. If it never appears in assembler output (and supposing the requested assembler tests for .scomm show that it does not appear in assembler output) then that resolves the .scommon questions - and indicates that it should *not* be added to the ABI since it's linker-internal - even if it would be better for the linker to know about *(SCOMMON) rather than hardcoding an internal name in linker scripts. -- Joseph S.

This version still defines R_C6000_SBR_GOT32 in include/elf/tic6x.h, although the corresponding ChangeLog entry is updated to use the correct name. (And while it has BFD_RELOC_* values for the new relocations, only BFD_RELOC_C6000_JUMP_SLOT, R_C6000_JUMP_SLOT is added to elf32_tic6x_reloc_map, without entries there for the other three relocations.)
