Age	Commit message (Collapse)	Author
2019-04-26	restore some code from b4a98c	Quentin Carbonneaux
	I had forgotten that %rip can only be used as base when there is no index. I also added a test which stresses addressing selection with and without constants.
2019-03-12	emit valid code for mem->mem copies	Quentin Carbonneaux

2019-03-09	add a stress test for phi spilling	Quentin Carbonneaux

2019-02-21	fix amd64 addressing mode matcher	Quentin Carbonneaux
	The numberer made some arranging choices when numbering arguments of an instruction, but these decisions were ignored when matching. The fix is to reconcile numbering and matching.
2019-02-18	mark phi arguments as escaping	Quentin Carbonneaux
	Thanks to Michael Forney for spotting this oversight and providing the test case. Note: because esc() leaves ABot unchanged, the assertion "a->type == ABot" on line 122 remains valid.
2019-02-06	2 bug fixes in rega	Quentin Carbonneaux
	The worst one was that "part 3" of rega() could break the critical invariant that two interferring temporaries get assigned different registers. This is fixed by being careful when changing the register of a temporary based on predecessor blocks. Thanks to Michael Forney for reporting these bugs and helping with the analysis.
2017-09-22	mark printf call as variadic in test	Quentin Carbonneaux

2017-07-30	fix dynamic stack allocs for amd64	Quentin Carbonneaux
	The arm64 might have the same problem but it is currently unable to handle them even in instruction selection. Thanks to Jean Dao for reporting the bug.
2017-04-08	new abi test for arm64 HFAs	Quentin Carbonneaux

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 }
2017-03-03	add another idiomatic C test (rega does no good)	Quentin Carbonneaux

2017-02-23	add simple idiomatic c test	Quentin Carbonneaux

2017-02-10	tests for variable argument lists	Quentin Carbonneaux

2017-02-10	support variable argument lists	Quentin Carbonneaux
	This change is backward compatible, calls to "variadic" functions (like printf) must now be annotated (with ...).
2016-12-12	new tests for the load optimization	Quentin Carbonneaux

2016-12-12	new eight queens test	Quentin Carbonneaux

2016-08-16	add support for unions in sysv abi	Quentin Carbonneaux

2016-04-22	refine fp conversion instructions	Quentin Carbonneaux

2016-04-13	add regression test for liveon bug	Quentin Carbonneaux

2016-04-13	add regression test for fixarg bug	Quentin Carbonneaux

2016-04-12	use a shift to divide by 2 in collatz	Quentin Carbonneaux

2016-04-12	fix type bug in abi3 test	Quentin Carbonneaux

2016-04-01	add huge mandelbrot brainfuck example	Quentin Carbonneaux

2016-04-01	add big test file for qbe	Quentin Carbonneaux

2016-03-29	make block labels per-function	Quentin Carbonneaux

2016-03-29	new layout, put LICENSE in root	Quentin Carbonneaux

2016-03-27	extract tests out of src	Quentin Carbonneaux
