I think this is wrong. If I compile this file myself and look at the debug
info, the debug info says it has cdecl calling convention.
```
D:\src\llvmbuild\ninja-x64>bin\llvm-pdbutil.exe dump -types foo.pdb | grep -C 5
simple_method
0x106D | LF_METHODLIST [size = 20]
- Method [type = 0x106B, vftable offset = -1, attrs = public
compiler-generated]
- Method [type = 0x106C, vftable offset = -1, attrs = public
compiler-generated]
0x106E | LF_FIELDLIST [size = 152]
- LF_VFUNCTAB type = 0x1056
- LF_ONEMETHOD [name = `simple_method`]
type = 0x1059, vftable offset = -1, attrs = public
- LF_ONEMETHOD [name = `virtual_method`]
type = 0x1059, vftable offset = 0, attrs = public intro virtual
- LF_ONEMETHOD [name = `static_method`]
type = 0x105A, vftable offset = -1, attrs = public static
D:\src\llvmbuild\ninja-x64>bin\llvm-pdbutil.exe dump -types -type-index=0x1059
foo.pdb
Types (TPI Stream)
============================================================
Showing 1 records.
0x1059 | LF_MFUNCTION [size = 28]
return type = 0x0003 (void), # args = 0, param list = 0x1011
class type = 0x1057, this type = 0x1058, this adjust = 0
calling conv = cdecl, options = None
```
Also, if I use clang-cl and pass the `-ast-dump` option, it will look like this:
```
| |-CXXMethodDecl 0x23869a32c38 <line:2:3, col:25> col:8 simple_method 'void ()'
| | `-CompoundStmt 0x23869a336f0 <col:24, col:25>
```
So it doesn't have `__attribute__((thiscall))` as you do in the test. Could
you double check this?
================
Comment at: lit/SymbolFile/NativePDB/ast-methods.cpp:33
+// CHECK: | |-CXXMethodDecl {{.*}} overloaded_method 'int (char)
__attribute__((thiscall))'
+// CHECK: | | `-ParmVarDecl {{.*}} 'char'
+// CHECK: | `-CXXMethodDecl {{.*}} overloaded_method 'int (char, int, ...)'

Parameter names should only be important once you are debugging inside of a
function, and at that point we will have already located the `S_GPROC32`
naturally. So I think it's ok for us to leave the parameter names blank, and
update the AST lazily whenever we encounter an `S_GPROC32` or `S_LPROC32`
naturally. We actually already parse the function parameter names in this
method (See `PdbAstBuilder::GetOrCreateFunctionDecl`), so in fact I think
everything will already mostly work, with only some minor code changes needed
to support both global functions as well as member functions.
================
Comment at: source/Plugins/SymbolFile/NativePDB/PdbAstBuilder.cpp:669-672
+ MemberFunctionRecord mfr;
+ llvm::cantFail(
+ TypeDeserializer::deserializeAs<MemberFunctionRecord>(cvt, mfr));
+ return CreateFunctionType(mfr.ArgumentList, mfr.ReturnType, mfr.CallConv);
----------------
I think there is a problem here.
