10 years agoWin64 ABI shouldn't extend integer type arguments.
Julien Lerouge [Tue, 26 Aug 2014 21:52:27 +0000 (21:52 +0000)]
Win64 ABI shouldn't extend integer type arguments.

Summary:
MSVC doesn't extend integer types smaller than 64bit, so to preserve
binary compatibility, clang shouldn't either.

For example, the following C code built with MSVC:

unsigned test(unsigned v);
unsigned foobar(unsigned short);
int main() { return test(0xffffffff) + foobar(28); }

Produces the following:

  0000000000000004: B9 FF FF FF FF     mov         ecx,0FFFFFFFFh
  0000000000000009: E8 00 00 00 00     call        test
  000000000000000E: 89 44 24 20        mov         dword ptr [rsp+20h],eax
  0000000000000012: 66 B9 1C 00        mov         cx,1Ch
  0000000000000016: E8 00 00 00 00     call        foobar

And as you can see, when setting up the call to foobar, only cx is overwritten.

If foobar is compiled with clang, then the zero extension added by clang means
the rest of the register, which contains garbage, could be used.

For example if foobar is:

unsigned foobar(unsigned short v) {
    return v;
}

Compiled with clang -fomit-frame-pointer -O3 gives the following assembly:

foobar:
  0000000000000000: 89 C8              mov         eax,ecx
  0000000000000002: C3                 ret

And that function would return garbage because the 16 most significant bits of
ecx still contain garbage from the first call.

With this change, the code for that function is now:

foobar:
  0000000000000000: 0F B7 C1           movzx       eax,cx
  0000000000000003: C3                 ret

This may increase the running time of EmitFunctionProlog, as we have to traverse
expandable arguments twice, but in further refactoring we will be able
to speed up EmitCall by passing already calculated CallArgsToIRArgsMapping to

Fix invalid test generation by utils/ABITest/ABITestGen.py when the same enum is generated more than once.

When generating records/unions, the same enum type may be generated more
than once (with different names). In these cases, the name of the enum
values are not sufficiently unique to prevent multiple declarations. E.g:
  typedef enum T3 { enum0val0 } T3;
  typedef T3 T2[3];
  typedef enum T4 { enum0val0 } T4;
  typedef union T1 { T2 field0; T4 field1; char field2; } T1;

Added a unique suffix to enum values so that multiple identical enum types do
not use the same enum value names.

One example of this bug is produced by:
  ABITestGen.py --no-unsigned --no-vector --no-complex --no-bool \

MS ABI: Don't always instantiate all members of dllexported class templates (PR20163)

Normally we mark all members of exported classes referenced to get them emitted.

However, MSVC doesn't do this for class templates that are implicitly specialized or
just have an explicit instantiation declaration. For such specializations, the members
are emitted when referenced.

The exception is the case when the dllexport attribute is propagated from a base class
to a base class template that doesn't have an explicit attribute: in this case all
methods of the base class template do get instantiated.
