Subject: [Bug dynamic-link/31218] PLT rewrite doesn't work on unrelocated definition
Date: Sat, 06 Jan 2024 18:59:17 +0000 [thread overview]
Message-ID: <bug-31218-131-jkZpGZ5Y6M@http.sourceware.org/bugzilla/> (raw)

--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
IFUNC is fine. The problem is with x32. On x32, PLT rewrite generates:
0xf7fbe060 <+0>: jmp 0x401030
0xf7fbe065 <+5>: int3
0xf7fbe066 <+6>: int3
0xf7fbe067 <+7>: int3
0xf7fbe068 <+8>: int3
0xf7fbe069 <+9>: int3
0xf7fbe06a <+10>: int3
0xf7fbe06b <+11>: int3
0xf7fbe06c <+12>: int3
0xf7fbe06d <+13>: int3
0xf7fbe06e <+14>: int3
0xf7fbe06f <+15>: int3
0xf7fbe060 + 0x401030 overflows.
