Fix MCDataAtom never calling remap when adding data. This patch fixes a small mistake in MCDataAtom::addData() where it doesn't ever call remap(): - if (Data.size() > Begin - End - 1) + if (Data.size() > End + 1 - Begin) remap(Begin, End + 1); This is currently not visible because of another bug is the disassembler, so the patch includes a unit test. Patch by Stephen Checkoway. llvm-svn: 192823

Fix a regression on the disassembling C API. The fix is easy. Unfortunately, we had 0 tests, so adding one was somewhat complicated. Thanks to Kevin Enderby for the report. llvm-svn: 221899

Disassembler.cpp
[MCDwarf] Fix encoding of line tables with weird custom parameters With poorly chosen custom parameters, the line table encoding logic would sometimes end up generating a special opcode bigger than 255, which is wrong. The set of default parameters that LLVM uses isn't subject to this bug. When carefully chosing the line table parameters, it's impossible to fall into the corner case that this patch fixes. The standard however doesn't require that these parameters be carefully chosen. And even if it did, we shouldn't generate broken encoding. Add a unittest for this specific encoding bug, and while at it, create some unit tests for the encoding logic using different sets of parameters. llvm-svn: 259334

DwarfLineTables.cpp
[MC] Fix undefined behavior in MCInstPrinter::formatHex Passing INT64_MIN to MCInstPrinter::formatHex triggers undefined behavior because the negation of -9223372036854775808 cannot be represented in type 'int64_t' (aka 'long long'). This patch puts a workaround in place to just print the hex value directly. A possible alternative involves using a small helper functions that uses (implementation) defined conversions to achieve the desirable value: static int64_t helper(int64_t V) { auto U = static_cast<uint64_t>(V); return V < 0 ? -U : U; } The underlying problem is that MCInstPrinter::formatHex(int64_t) returns a format_object<int64_t> and should really return a format_object<uint64_t>. However, that's not possible because formatImm needs to be able to print both as decimal (where a signed is required) and hex (where we'd prefer to always have an unsigned). format_object<int64_t> formatImm(int64_t Value) const { return PrintImmHex ? formatHex(Value) : formatDec(Value); } Differential revision: https://reviews.llvm.org/D67236 llvm-svn: 371159

Invert the MC -> Object dependency. Now that we have a lib/MC/MCAnalysis, the dependency was there just because of two helper classes. Move the two over to MC. This will allow IRObjectFile to parse inline assembly. llvm-svn: 212248

Implement wave32 DWARF register mapping Implement the DWARF register mapping described in llvm/docs/AMDGPUUsage.rst. This enables generating appropriate DWARF register numbers for wave64 and wave32 modes.
