Managed to find https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/assembler/idalangref_cmp_instr.html, but is GCC using a different order, for registers?

[vmlemon]

According to https://patchwork.ozlabs.org/patch/678943/#1492141 (thanks to zid, in #osdev, on FreeNode, for pointing this out!), the BinUtils folks changed the mnemonic syntax, back in 2016. Should we be using cmpd, or cmpw, though?

[vmlemon]

Needed to do this, for both POWER3/4 (changing to cmpd), but the next issue is the lack of asmsyms.h

[vmlemon]

According to http://www.osfree.org/doku/en:docs:kernel:build, there's some extra steps, to make various header files:

make tcb_layout.h
make asmsyms.h
make kdb_class_helper.h
make kdb_autogenerated_protos.h

[vmlemon]

That seems to bail, but I did find https://lists.gnu.org/archive/html/l4-hurd/2005-01/msg00149.html

[vmlemon]

Applied workarounds, for both P3/4 versions, in 0a4ae8f. This at least gets us out of the rut, involving the Assembly code.

[vmlemon]

As part of #9, we imported a huge heap of PowerPC 64-bit code, from the NICTA Pistachio 1.1 distribution, that changes the ABI, and API in places, so we need to go back, and see if the workaround for cmp is still necessary, or if it needs to be reapplied, in places.

[vmlemon]

On our MiniCloud PPCBE instance, we get to this stage, with the latest changes:

[vmlemon]

With some evil hacks in the NICTA_Pistachio_Mainline_FCL branch, we now successfully generate these very-essential files:

 create mode 100644 kernel/rpb8/include/asmsyms.h
 create mode 100644 kernel/rpb8/include/tcb_layout.h
 create mode 100644 kernel/rpb8/src/glue/v4-powerpc64/asmsyms.o

The next mission is fixing this...

Looking at https://github.com/vmlemon/Orion/search?p=5&q=cmp&unscoped_q=cmp, we still have some PPC code, that uses cmp, but we haven't gotten as far as building it, yet.

[vmlemon]

Express-patched all of the user/serv/sigma0/crt0-powerpc64.S, user/apps/l4test/powerpc64/crt0.S, user/util/piggybacker/ofppc/crt0.S, user/util/piggybacker/ofppc64/crt0.S, kernel/src/platform/ofg5/head.S, pistachio--devel--1.1--version-0/kernel/src/platform/ofg5/head.S, pistachio--devel--1.1--version-0/kernel/src/platform/ofpower3/head.S, pistachio--devel--1.1--version-0/kernel/src/platform/ofpower4/head.S, kernel/src/platform/ofppc/startup.S, and pistachio--devel--1.1--version-0/kernel/src/platform/ofppc/startup.S versions that we have.

We don't seem to use cmp much (seems to be once, per-file), so there wasn't much to do, but tediously adding a 'd' to every instance, by hand... I'm also unsure if it's necessary to do it for 32-bit PPC (or if it breaks things), but I patched those versions, too.

Going to close this low-hanging bug, now.
