Bug #: 14603
Summary: no reloc emitted for ld generated veneers for ARM
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: ld
AssignedTo: unassig...@sourceware.org
ReportedBy: marcin.bu...@gmail.com
Classification: Unclassified

testcase
The simple test case provided shows that 0x80000000 constant used as jump
address in veneer generated by ld has no reloc associated. I believe this is a
bug (or inconsistency at least). I noticed this working on bFLT loader for the
target with memory split - fast internal ram and regular dram. With current ld
behavior runtime relocation is broken by this.
The workaround is to use -mlong-calls when compiling C sources but this imposes
performance penalty as well as does not solve the problem of asm files.
Tested with 2.20.1 as well as with current snapshot.
