Subject: [PATCH] Use local label in inline asm, avoid symbol duplication
|
|
|
f2d453 |
|
|
|
f2d453 |
The global label "unsupported" may lead to duplicated symbols
|
|
|
f2d453 |
when the function is inlined in multiple places. This may happen
|
|
|
f2d453 |
in any case, but using LTO exposes this problem reliably.
