Jeremy Rand 3def47d32f Make a step towards getting memory reads working. 2016-07-17 22:46:47 -04:00
Jeremy Rand f8d884f5f9 Get my first test source file compiling into valid ORCA/M assembly source. 2016-05-13 22:56:40 -04:00
Jeremy Rand 4cc95195f4 Get rid of the .globl directive in the assembly output. 2016-05-12 20:39:27 -04:00
Jeremy Rand acc21bea81 Get rid of the .text directive in the assembly output by creating a target object file class specific for the 65816. 2016-05-12 20:13:51 -04:00
Jeremy Rand 30e52d00c8 Get rid of the .size stuff in the assembly output and format the instructions better. 2016-04-22 00:05:07 -04:00
Jeremy Rand 48276b8f1f Add code to emit the case, keep and segment start/end directives in the output assembly file. Indent the instructions as ORCA/M expects. 2016-04-20 23:48:48 -04:00
Jeremy Rand f0e0e4ec4a Start creating the infrastructure for producing valid assembly for ORCA/M or Merlin. 2016-04-19 23:39:53 -04:00
Jeremy Rand 2253ae62fc Get the answerToTheUltimateQuestion() function to compile to something approximating 65816 assembly. With this commit, I can compile the simplest of functions but it is a start. 2016-04-07 23:15:53 -04:00
Jeremy Rand e013351e03 Clean up some problems in the register specification in the instruction format. 2016-02-27 23:31:12 -05:00
Jeremy Rand b95686b032 Add some more debug around which node is being visited. 2016-02-10 23:30:20 -05:00
Jeremy Rand 52705f393a More infrastructure required for the basic function which returns a constant integer. 2016-02-09 22:30:11 -05:00
Jeremy Rand 4fb15c1a07 Disable the fake direct page registers which are wider than 16-bits for now to workaround a problem. LLVM seems to promote everything to 32-bit if you say the machine has 32-bit or better registers even if I have indicated that the native bit width is 16. Disabling these gets me one step closer to my first successful compile. 2015-09-03 23:41:00 -04:00
Jeremy Rand 74cb03d2f6 Fix the calling convention for return values. I believe the way this works is that you specify the width of the single register and a list of registers to return values in for anything bigger. By having a return convention for [i32], I seem to have been telling LLVM that it can return a 32-bit value in X which it cannot do. 2015-08-31 23:30:50 -04:00
Jeremy Rand c09c887891 Adopt the standard LLVM debug infrastructure for WDC_LOG(). This way, debugging can be turned on/off at the command line using the "clang -mllvm -debug ..." option. 2015-08-28 23:11:18 -04:00
Jeremy Rand e7deb74a84 Adjust the target and ABI info for WDC65816 in clang. 2015-08-06 23:01:00 -04:00
Jeremy Rand 5d8601e987 Some more implementation towards my first successful compile of a simple function. 2015-08-06 00:20:12 -04:00
Jeremy Rand 2e2ecfb186 More implementation of LowerFormalArguments() and LowerReturn() 2015-08-05 00:22:22 -04:00
Jeremy Rand 4849b050ce Start adding an implementation for LowerFormalArguments(). 2015-08-03 23:42:37 -04:00
Jeremy Rand 4862a6612b Add placeholder implementations of a couple more methods. At this point, I can "compile":
int theAnswer(void)
return 42;

It compiles in the sense that clang executes to the end without crashing but the .s file it produces is useless.  But another small step forward.

Jeremy Rand 9d6408d419 Add register classes. 2015-07-30 23:12:12 -04:00
Jeremy Rand e3aaebf907 Fix crash which was caused by not attempting to compute register properties. Now, the register properties fail to be computed because "No integer registers defined!" 2015-07-30 01:48:59 -04:00
Jeremy Rand b11140166b Add some logs to help trace what i happening when executing. 2015-07-28 23:15:15 -04:00
Jeremy Rand 6bfb66385d Add a logging mechanism to make it easier to debug the 65816 code. 2015-07-28 00:18:06 -04:00
Jeremy Rand 39070eb1d0 Model the direct page as a series of 16-bit, 32-bit and 64-bit integer registers and also a series of 32-bit and 64-bit float registers. Reserve the 0th 32-bit integer register in the direct page for use as a frame pointer. 2015-07-23 23:45:42 -04:00

Jeremy Rand 26846cab41 I have no idea why I thought I did't need a subtarget. I do need one so I have added it. 2015-07-17 23:57:48 -05:00
