With tilepro removal, the uppercase instruction are not anymore
required to be defines as potentially macros. This is a
mechanical change done by the following shell script:
---
INSNS="LD LD4U ST ST4 BNEZ BEQZ BEQZT BGTZ CMPEQI CMPEQ CMOVEQZ CMOVNEZ"
FILES=$(find sysdeps/tile sysdeps/unix/sysv/linux/tile -iname *.S)
for insn in $INSNS; do
repl=$(echo $insn | tr '[:upper:]' '[:lower:]')
sed -i 's/\b'$insn'\b/'$repl'/g' $FILES
done
---
Checked with a build for tilegx-linux-gnu and tilegx-linux-gnu-32 with
and without the patch, there is no difference in generated binary with
a dissassemble.

Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this
patch eliminates its use for _dl_init. Since _dl_init was already
declared with hidden visibility, creating a second hidden alias for it
was completely pointless, so this patch replaces all uses of
_dl_init_internal with plain _dl_init instead of using hidden_proto /
hidden_def (which are only needed when you want a hidden alias for a
non-hidden symbol; it's quite possible there are cases where they are
used but don't need to be because the symbol in question is not part
of the public ABI and is only used within a single library, so using
attributes_hidden instead would suffice).
Tested for x86_64 that installed stripped shared libraries are
unchanged by the patch.

I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy,
along with the linux-generic ports infrastructure. Beyond the README
update, the move was just
git mv ports/sysdeps/tile sysdeps/tile
git mv ports/sysdeps/unix/sysv/linux/tile \
sysdeps/unix/sysv/linux/tile
git mv ports/sysdeps/unix/sysv/linux/generic \
sysdeps/unix/sysv/linux/generic
I updated the relevant ChangeLogs along the lines of the ARM move
in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.
