Bug ID: 22342
Summary: Assertion `StringIndexMap.count(s) && "String is not
in table!"' failed.
Product: clang
Version: trunk

OS: Linux

Hi,
Clang fails to compile the　attached code, which includes a function whose
section and name is the same, and specified as an alias.
<<<<<[section.c]
void sub1(void) __attribute__(( section("sub1"), alias("sub2") ));
void sub2(void) { return; }
>>>>>
% clang ./section.c -O0 -c
clang: /home/kama/llvm/include/llvm/MC/StringTableBuilder.h:53: size_t
llvm::StringTableBuilder::getOffset(llvm::StringRef): Assertion
`StringIndexMap.count(s) && "String is not in table!"' failed.
...
Clang is able to emit an assembler file, but fails to emit an object while gcc
succeeds.
Adding to this, there is a difference in assembler files of gcc and clang.
The section of function b code is in .section a by clang and .text by gcc.
I don'n know which section is correct, but at least the assertion must be
fixed.
