[LLVMdev] Error with Gold Linker during LTO

where the bl 0 causes a seg fault.

[LLVMdev] Error with Gold Linker during LTO
We've found an error during the use of LTO that appears to happen only
during the use of the gold linker.
We essentially have a file which is compiled *without* LTO:
f1() {
h1();
}
And a second file that is compiled/linked *with* LTO:
f2() {
f1();
h1();
}
This second file has the function h1() inlined during LTO.
