George Koehler 41f3bf78cd Edit descr for linuxppc. Use powerpc.descr of ego. 
ack -mlinuxppc -O4 now runs more phases of ego, including the register
allocation phase, so ncg emits better code.

Set MACHOPT_F=-m3 as I did it for osxppc; see commit 0c2b6f5.

Remove CC_ALIGN=-Vr so bitfields agree with gcc for PowerPC Linux.

Remove unused C_LIB and OLD_C_LIB.

David Given 0e10329876 Fix an issue throughout where B couldn't be built by ackprogram due to symbol 
laziness.

David Given 4485d89b23 Hook the B compiler up to the compiler driver. 2016-11-27 20:48:07 +01:00
David Given 5bce5fc4da Change the extension used by Basic files for .b to .bas, to avoid conflicts 
with B.

David Given 48e74f46fc Add the very experimental qemuppc plat, intended to generate minimal images 
which can be emulated using qemu (for, hopefully, a test suite). Currently it
generates images which won't run because there's no RAM.

David Given 8c3670483f Get top working with the PowerPC; use it to eliminate useless branches and 
moves.

David Given 5f0164db62 Bolt mcg into the PowerPC backend. It doesn't build yet, but it is generating 
*some* code.

George Koehler 865ef629dd Multiple tweaks to plat/linuxppc/descr 
Don't define __POWERPC.  I don't know any other compiler that defines
__POWERPC and don't want to invent a new macro.  Apple's gcc 4.0.1
from Xcode 2.5 defines __ppc__, _ARCH_PPC, __POWERPC__.  Debian's gcc
4.9.2-10 defines _ARCH_PPC, __PPC__, __powerpc__, __PPC, __powerpc,
PPC, powerpc.

Move the base vm address from 0x80000000 down to 0x10000000, as this
is where Debian loads /bin/true.  This is still higher than the base
addresses for linux386 and linux68k.

Sync led's arguments with linux386.

David Given 45a950571d Mostly add support for the experimental and largely broken linuxppc platform. 
(Doesn't quite build.)

Linuxes all build.
