Bug ID: 26152
Summary: Linker wronlgy renames an external function
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Linker
Assignee: unassignedb...@nondot.org
Reporter: eugeni.stepa...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
I'm linking 2 modules, where the first calls an external function A(), and the
second defines A() and also an alias for it.
The resulting module does not export A(). Instead it exports A.1().
The behavior depends on the order of modules in the link command line.
$ cat 1.ll
define void @B() {
call void @A()
ret void
}
declare void @A()
$ cat 2.ll
@C = alias void (), void ()* @A
define void @D() {
call void @C()
ret void
}
define void @A() {
ret void
}
$ llvm-link 1.ll 2.ll -S -o -
; ModuleID = 'llvm-link'
@C = alias void (), void ()* @A.1
define void @B() {
call void @A.1()
ret void
}
define void @D() {
call void @C()
ret void
}
define void @A.1() {
ret void
}
