-Likewise, binutils has no idea about any of these new targets either, so we
-fix that up too.. now we're able to actually build a real toolchain for
-sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
-inept targets than that one, really. Go look, I promise).

-Subject: [PATCH] Fix alignment for the first section frag on xtensa
-
-Linking object files produced by partial linking with link-time
-relaxation enabled sometimes fails with the following error message:
-
-dangerous relocation: call8: misaligned call target: (.text.unlikely+0x63)
-
-This happens because no basic block with an XTENSA_PROP_ALIGN flag in the
-property table is generated for the first basic block, even if the
-.align directive is present.
-It was believed that the first frag alignment could be derived from the
-section alignment, but this was not implemented for the partial linking
-case: after partial linking first frag of a section may become not
-first, but no additional alignment frag is inserted before it.
-Basic block for such frag may be merged with previous basic block into
-extended basic block during relaxation pass losing its alignment
-restrictions.
-
-Fix this by always recording alignment for the first section frag.

-Subject: [PATCH] Fix xtensa ld segfault when linking linux modules
-
-is_inconsistent_linkonce_section makes an assumption that section name
-that starts with ".gnu.linkonce.prop." has one more dot in its suffix.
-However gas generates such section name by insertion of "prop." right
-after ".gnu.linkonce." part of the name of the original section. So, for
-section named ".gnu.linkonce.this_module" corresponding property section
-name does not satisfy the assumption. Such section names are common in
-linux modules. This bug was exposed by the patch "a35d5e8 Fix alignment
-for the first section frag on xtensa", that makes gas produce property
-section for each section that has ".align" directive in it.
-
-Use suffix that immediately follows ".gnu.linkonce.prop." when there are
-no more dots following it.

-Subject: [PATCH] xtensa: fix signedness of gas relocations
-
-Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
-offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
-substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
-8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
-directive. Revert this part and add test.

- substitutions for BFD_RELOC_* as unsigned.

-Subject: [PATCH] xtensa: fix .init/.fini literals moving
-
-Despite the documentation and the comment in xtensa_move_literals, in
-the presence of --text-section-literals and --auto-litpools literals are
-moved from the separate literal sections into .init and .fini, because
-the check in the xtensa_move_literals is incorrect.
-
-This moving was broken with introduction of auto litpools: some literals
-now may be lost. This happens because literal frags emitted from .init
-and .fini are not closed when new .literal_position marks new literal
-pool. Then frag_align(2, 0, 0) changes type of the last literal frag to
-rs_align. rs_align frags are skipped in the xtensa_move_literals. As a
-result fixups against such literals are not moved out of .init.literal/
-.fini.literal sections producing the following assembler error:
-
- test.S: Warning: fixes not all moved from .init.literal
- test.S: Internal error!
-
-Fix check for .init.literal/.fini.literal in the xtensa_move_literals
-and don't let it move literals from there in the presence of
---text-section-literals or --auto-litpools.
