<pre>Use clang 6.0.0.1 to compile this simple code, the relocation for
.gcc_except_table is R_X86_64_32:
$ cat x.cpp
int main () {
try
{
throw 20;
}
catch (int e)
{
}
return 0;
}
$ clang --target=x86_64 -m64 -mcmodel=kernel -c x.cpp
$ $ objdump -Dr x.o|grep .gcc_except_table
Disassembly of section .gcc_except_table:
31: R_X86_64_32 .gcc_except_table
But if use clang 5.0.0.3 to compile the same code, the relocaction type is
R_X86_64_64 for .gcc_except_table.
Is the difference between 5.0.0.3 and 6.0.0.1 expected? or a problem we should
fix?</pre>
