Clarify when we can avoid creating names for temp symbols.

Some temporary symbols are created by MC itself. These symbols are never used
for lookup and are never included in the object symbol table, so we can
avoid creating a name for them.

Other temporaries are created by CodeGen or by the user by explicitly asking
for a name starting with .L (or L on MachO).

These temporaries behave like regular symbols, we just try to avoid including
them in the object symbol table, but sometimes they end up there:

const char *foo() {
  return "abc" + 3;
}

will have a relocation pointing to a .L symbol.

It just so happens that almost all MC created temporary has the AlwaysAddSuffix
option and CodeGen/user created ones don't.

One interesting future optimization would be to use unnamed symbols for
all temporaries, but that would require use an st_name of 0 or
having the object writer create the names if a symbol does end up in the
symbol table.

9 years ago[x86-64 ABI] Fix for PR23082: an assertion failure when passing/returning a wrapper...
Andrea Di Biagio [Tue, 2 Jun 2015 19:34:40 +0000 (19:34 +0000)]
[x86-64 ABI] Fix for PR23082: an assertion failure when passing/returning a wrapper union in a full YMM register.

This patch fixes an assertion failure in method
'X86_64ABIInfo::GetByteVectorType'.

Method 'GetByteVectorType' (in TargetInfo.cpp) is responsible
for mapping a QualType 'Ty' (for an argument or return value) to an LLVM IR
type that, according to the ABI, must be passed in a XMM/YMM vector register.

When selecting the IR vector type, method 'GetByteVectorType' always tries to
choose the "best" IR vector type for the 'Ty' in input. In particular, if Ty
is a wrapper structure, it keeps unwrapping it until it finds a vector type VTy.
That VTy is the "preferred IR type".

However, function 'isSingleElementStructure' (used to unwrap structures) does
not know how to look through union types. So, before this patch, if Ty was in
a nest of wrapper structures with at least two union types, we would have
triggered an assertion failure (added at revision 230971).

With this patch, if method 'GetByteVectorType' fails to find the preferred
vector type, we just return a valid (although potentially 'less friendly')
vector type based on the type size. So, rather than asserting on an 'unexpected'
'Ty' in input, we conservatively return vector type <2 x double> if Ty is 16
bytes, or <4 x double> if Ty is 32 bytes.
