## This test makes sure we don't shrink .relr.dyn, otherwise its size may
## oscillate between 2 words and 3 words.

## The test is very sensitive to the exact section sizes and offsets,
## make sure .data is located at a page boundary.

# CHECK: .relr.dyn needs 1 padding word(s)

# RELR-NEXT:   0x2F40 R_AARCH64_RELATIVE - 0x0

## If .data is at 0x3000, the relocation will be encoded by the second word.
## If we shrink .relr.dyn, the end of .dynamic will be at 0x2ff8 and .data
## will be at 0x3ff8, we will need the third word to encode this relocation,
## which will cause .relr.dyn to expand again.
