~cnx/roux - Alternative QBE compiler

Age	Commit message (Collapse)	Author
2022-02-17	add rv64 backend	Michael Forney
	It is mostly complete, but still has a few ABI bugs when passing floats in structs, or when structs are passed partly in register, and partly on stack.
2019-04-26	Fix config.h dependency when OBJDIR != obj	Michael Forney

2019-04-24	Fix default config.h for arm64	Michael Forney

2017-04-08	add handy src target to the Makefile	Quentin Carbonneaux
	Intended usage: c_count `make src` (or similar).
2017-04-08	enable arm64 tests	Quentin Carbonneaux
	The vararg tests had to be changed because va_list is 32-bit wide on arm. The astute reader will notice that the way we pass va_list values is wrong, we should be using the ':valist' type as defined below instead of 'l'. But eh, that works for now, because of the ABI. type :valist = align 8 { 32 }
2017-04-08	add cross testing for arm64	Quentin Carbonneaux

2017-04-08	new arm64 backend, yeepee	Quentin Carbonneaux

2017-04-08	prepare for multi-target	Quentin Carbonneaux
	This big diff does multiple changes to allow the addition of new targets to qbe. The changes are listed below in decreasing order of impact. 1. Add a new Target structure. To add support for a given target, one has to implement all the members of the Target structure. All the source files where changed to use this interface where needed. 2. Single out amd64-specific code. In this commit, the amd64 target T_amd64_sysv is the only target available, it is implemented in the amd64/ directory. All the non-static items in this directory are prefixed with either amd64_ or amd64_sysv (for items that are specific to the System V ABI). 3. Centralize Ops information. There is now a file 'ops.h' that must be used to store all the available operations together with their metadata. The various targets will only select what they need; but it is beneficial that there is only one place to change to add a new instruction. One good side effect of this change is that any operation 'xyz' in the IL now as a corresponding 'Oxyz' in the code. 4. Misc fixes. One notable change is that instruction selection now generates generic comparison operations and the lowering to the target's comparisons is done in the emitter. GAS directives for data are the same for many targets, so data emission was extracted in a file 'gas.c'. 5. Modularize the Makefile. The Makefile now has a list of C files that are target-independent (SRC), and one list of C files per target. Each target can also use its own 'all.h' header (for example to define registers).
