Bug ID: 19647
Summary: accepts invalid
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: MC
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
MC currently accepts
zed = foo +2
call zed@PLT
but there is no way to represent that in ELF if foo is undefined. What is being
requested is that (on x86_64):
* we produce a R_X86_64_PLT32 with and addend of -4 to a PLT location.
* That the plt entry in turn should refer to foo+2.
It is the second part that cannot be represented. The entry will always just
refer to a symbol and there is no way to define a symbol that is some undefined
symbol + 2.
