David Given dcba03646b Treebuilder now gets to the bottom of my test file, merrily generating
(probably horribly broken) IR.
2016-09-19 23:30:41 +02:00
David Given 6ce2495aeb Store the EM code up front and build the basic block graph *before*
generating the IR code. Lots more IR code.

George Koehler 5b69777647 Rename our pseudo-opcode 'la' to 'li32'.
GNU as has "la %r4,8(%r3)" as an alias for "addi %r4,%r3,8", meaning
to load the address of the thing at 8(%r3).  Our 'la', now 'li32',
makes an addis/ori pair to load an immediate 32-bit value.  For
example, "li32 r4,23456789" loads a big number.

George Koehler 9db305b338 Enable the Hall check again, and get powerpc to pass it.
Upon enabling the check, mach/powerpc/ncg/table fails to build as ncgg
gives many errors of "Previous rule impossible on empty stack".  David
Given reported this problem in 2013:
  https://sourceforge.net/p/tack/mailman/message/30814694/

Commit c93cb69 commented out the error in util/ncgg/cgg.y to disable
the Hall check.  This commit enables it again.  In ncgg, the Hall
check is checking that a rule is possible with an empty fake stack.
It would be possible if ncg can coerce the values from the real stack
to the fake stack.  The powerpc table defined coercions from STACK to
{FS, %a} and {FD, %a}, but the Hall check didn't understand the
coercions and rejected each rule "with FS" or "with FD".

This commit removes the FS and FD tokens and adds a new group of FSREG
registers for single-precision floats, while keeping FREG registers
for double precision.  The registers overlap, with each FSREG
containing one FREG, because it is the same register in PowerPC
hardware.  FS tokens become FSREG registers and FD tokens become FREG
registers.  The Hall check understands the coercions from STACK to
FSREG and FREG.  The idea to define separate but overlapping registers
comes from the PDP-11 table (mach/pdp/ncg/table).

This commit also removes F0 from the FREG group.  This is my attempt
to keep F0 off the fake stack, because one of the stacking rules uses
F0 as a scratch register (FSCRATCH).

George Koehler 03b067e1d5 Add the missing .lar4 and .sar4 for powerpc.
Inspired by the sparc code (mach/sparc/libem/lar.s).  My powerpc code
might still have bugs, but it's enough for examples/hilo.mod to work.

May need to 'make clean' or touch a build.lua file, so ackbuilder can
notice the new lar4.s and sar4.s files and build them.

David Given 80cb6ba927 Eliminate the RELOH2 relocation, as it never worked --- the address would be
calculated incorrectly because of overflow errors.

Replace it with an extended RELOPPC relocation which understands addis/ori
pairs; add an la pseudoop to the assembler which generates these and the
appropriate relocation. Make good.

George Koehler 0131ca4d46 Delete 689 undead files.
These files "magically reappeared" after the conversion from CVS to
Mercurial.  The old CVS repository deleted these files but did not
record *when* it deleted these files.  The conversion resurrected these
files because they have no history of deletion.  These files were
probably deleted before year 1995.  The CVS repository begins to record
deletions around 1995.

These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted.  There is no way to fix
this, because the CVS repository provides no dates of deletion.
