Bug ID: 15408
Summary: undefined reference to '.Lline_table_start1' when
generating .s from output of llvm-link
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Linker
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
The version of clang I tested with includes r174445, r174479, and r174785,
The following sequence of commands:
echo "int main() { return 0; }" | clang -g -x c -c - -emit-llvm -o main.bc
echo "int foo() { return 0; }" | clang -g -x c -c - -emit-llvm -o foo.bc
llvm-link main.bc foo.bc -o link.bc
clang -g link.bc -save-temps
produces:
/usr/bin/ld: link.o:(.debug_info+0x69): error: undefined reference to
'.Lline_table_start1'
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
Note that '-save-temps' is not required to reproduce the problem for targets
that do not have an integrated assembler.
