[LLVMdev] Problem with __inline keyword
...ernal symbols.
Specifically, if I have the following test program:
__inline int foo()
{
return 5;
}
int bar()
{
return foo();
}
Compiling for ARM with no optimizations yields this:
00000000 <bar>:
0: e92d4800 push {fp, lr}
4: e1a0b00d mov fp, sp
8: e24dd008 sub sp, sp, #8
c: ebfffffe bl 0 <foo>
10: e58d0004 str r0, [sp, #4]
14: e1a0d00b mov sp, fp
18: e8bd4800 pop {fp, lr}
1c: e12fff1e bx lr
As you can see, no inlining took place, so there is still a refere...

[LLVMdev] Error with Gold Linker during LTO
So you see the issue as well in ARM? When doing a
objdump -D weakMainO1.exe | grep -A 10 "<_ZN1C13caller_methodEv>:"
I see:
00008b88 <_ZN1C13caller_methodEv>:
8b88: e92d4800 push {fp, lr}
8b8c: e1a0b00d mov fp, sp
8b90: e24dd008 sub sp, sp, #8
8b94: e58d0004 str r0, [sp, #4]
8b98: e59d0004 ldr r0, [sp, #4]
8b9c: ebffdd17 bl 0 <__preinit_array_end>
8ba0: e1a0d00b mov sp, fp
8ba4: e8bd4800 pop {fp, lr}
8ba8: e12fff1e bx lr
where the bl 0 causes a seg fault.
I'll check x86_64, but cu...

[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.
The resulting executable fails because the symbol for h1
