Subject: [Bug dynamic-link/31662] Stack not aligned at _start when calling ld.so explicitly
Date: Sun, 21 Apr 2024 07:27:53 +0000	[thread overview]
Message-ID: <bug-31662-131-yzbBnVl4ZO@http.sourceware.org/bugzilla/> (raw)
In-Reply-To: <bug-31662-131@http.sourceware.org/bugzilla/>

--- Comment #4 from Felix Potthast <mail@felix-potthast.de> ---
@Andreas Schwab:
Sure, but the elf entry point is not a normal function and there is no return
address on the stack. It is not called but jumped to at the end of
_dl_start_user.

@H.J.Lu:
Yes, this is intentional. The point is: the stack pointer is guaranteed to be
16-byte aligned at process entry by the ABI. So i should'nt have to align it
before jumping into memcpy.
