* [MIR] Add support for debug metadata for fixed stack objectsFrancis Visoiu Mistrih2018-04-251-13/+21
| | | | | | | | | | | | | | | Debug var, expr and loc were only supported for non-fixed stack objects. This patch adds the following fields to the "fixedStack:" entries, and renames the ones from "stack:" to: * debug-info-variable * debug-info-expression * debug-info-location Differential Revision: https://reviews.llvm.org/D46032 llvm-svn: 330859

* [GlobalISel] Print/Parse FailedISel MachineFunction propertyRoman Tereshin2018-02-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | FailedISel MachineFunction property is part of the CodeGen pipeline state as much as every other property, notably, Legalized, RegBankSelected, and Selected. Let's make that part of the state also serializable / de-serializable, so if GlobalISel aborts on some of the functions of a large module, but not the others, it could be easily seen and the state of the pipeline could be maintained through llc's invocations with -stop-after / -start-after. To make MIR printable and generally to not to break it too much too soon, this patch also defers cleaning up the vreg -> LLT map until ResetMachineFunctionPass. To make MIR with FailedISel: true also machine verifiable, machine verifier is changed so it treats a MIR-module as non-regbankselected and non-selected if there is FailedISel property set.

* [MIR] Repurposing '$' sigil used by external symbols. Replacing with '&'.Puyan Lotfi2018-01-101-1/+1
| | | | | | | | | | Planning to add support for named vregs. This puts is in a conundrum since physregs are named as well. To rectify this we need to use a sigil other than '%' for physregs in MIR. We've settled on using '$' for physregs but first we must repurpose it from external symbols using it, which is what this commit is all about. We think '&' will have familiar semantics for C/C++ users. llvm-svn: 322146

* Mark all library options as hidden.Zachary Turner2017-12-011-1/+2
| | | | | | | | | | | | | | | | | These command line options are not intended for public use, and often don't even make sense in the context of a particular tool anyway. About 90% of them are already hidden, but when people add new options they forget to hide them, so if you were to make a brand new tool today, link against one of LLVM's libraries, and run tool -help you would get a bunch of junk that doesn't make sense for the tool you're writing. This patch hides these options. The real solution is to not have libraries defining command line options, but that's a much larger effort and not something I'm prepared to take on.

* MIR: Print the register class or bank in vreg defsJustin Bogner2017-10-241-12/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | This updates the MIRPrinter to include the regclass when printing virtual register defs, which is already valid syntax for the parser. That is, given 64 bit %0 and %1 in a "gpr" regbank, %1(s64) = COPY %0(s64) would now be written as %1:gpr(s64) = COPY %0(s64) While this change alone introduces a bit of redundancy with the registers block, it allows us to update the tests to be more concise and understandable and brings us closer to being able to remove the registers block completely. Note: We generally only print the class in defs, but there is one exception. If there are uses without any defs whatsoever, we'll print the class on all uses. I'm not completely convinced this comes up in meaningful machine IR, but for now the MIRParser and MachineVerifier both accept that kind of stuff, so we don't want to have a situation where we can print something we can't parse. llvm-svn: 316479

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This re-applies commit r313685, this time with the proper updates to the test cases. Original commit message: Unreachable blocks in the machine instr representation are these weird empty blocks with no successors. The MIR printer used to not print empty lists of successors. However, the MIR parser now treats non-printed list of successors as "please guess it for me". As a result, the parser tries to guess the list of successors and given the block is empty, just assumes it falls through the next block (if any). For instance, the following test case used to fail the verifier. The MIR printer would print entry / \ true (def) false (no list of successors) | split.true (use) The MIR parser would understand this: entry / \ true (def) false | / <-- invalid edge split.true (use) Because of the invalid edge, we get the "def does not dominate all uses" error. The fix consists in printing empty successor lists, so that the parser knows what to do for unreachable blocks. rdar://problem/34022159 llvm-svn: 313696
