[WebAssembly] Convert the remaining unit tests to the new wasm-object-file target. To facilitate this, add a new hidden command-line option to disable the explicit-locals pass. That causes llc to emit invalid code that doesn't have all locals converted to get_local/set_local, however it simplifies testwriting in many cases. llvm-svn: 296540

Improve virtual register handling when computing debug information Summary: Some backends, like WebAssembly, use virtual registers instead of physical registers. This crashes the DbgValueHistoryCalculator pass, which assumes that all registers are physical. Instead, skip virtual registers when iterating aliases, and assume that they are clobbered.

[CodeGen] Print "%vreg0" as "%0" in both MIR and debug output As part of the unification of the debug format and the MIR format, avoid printing "vreg" for virtual registers (which is one of the current MIR possibilities). Basically: * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E "s/%vreg([0-9]+)/%\1/g" * grep -nr '%vreg' . and fix if needed * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E "s/ vreg([0-9]+)/ %\1/g" * grep -nr 'vreg[0-9]\+' . and fix if needed Differential Revision: https://reviews.llvm.org/D40420 llvm-svn: 319427

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.

[WebAssembly] Basic support for Wasm object file encoding. With the "wasm32-unknown-unknown-wasm" triple, this allows writing out simple wasm object files, and is another step in a larger series toward migrating from ELF to general wasm object support. Note that this code and the binary format itself is still experimental. llvm-svn: 296190

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144
