[LLVMdev] Function inline causes crash in clang for .ast to .s

[rajesh viswabramana]

Hi,

Clang crashes when tried to compile from .ast to .s for below sample code,

inline-test.c
**
*extern inline int func1 (void) { return 0; }
inline int func1 (void) { return 1; }*

clang *works fine* for .c -> .s,
*>clang inline-test.c -std=c99 -fgnu89-inline -S -o inline-test.s *

But *crashes* when tried to generate .s from .ast for same file,
*>clang inline-test.c -std=c99 -fgnu89-inline -emit-ast -o inline-test.ast*
*>clang inline-test.ast -std=c99 -fgnu89-inline -S -o inline-test.s*

clang-3.2: $HOME/llvm/tools/clang/lib/CodeGen/CodeGenFunction.cpp:342: void
clang::CodeGen::CodeGenFunction::*StartFunction*(clang::GlobalDecl,
clang::QualType, llvm::Function*, const clang::CodeGen::CGFunctionInfo&,
const clang::CodeGen::FunctionArgList&, clang::SourceLocation):
Assertion `*CurFn->isDeclaration()
&& "Function already has body?"*' failed.

>From crash message it seems Codegen is already emitted for inline function.

Crash occurs only if tried to generate assembly out of ast file.
