<div dir="ltr"><div>Can you provide the testcase to show the case which I mentioned in the pr13302? Which is that an ifunc with a dynamic jump slot calls another ifunc, and are not in the rel.dyn.

1. When an ifunc is referenced by a pointer, the relocation of<br>
the pointer in .rela.plt would be overwritten by normal ifunc call.<br>
2. R_RISCV_IRELATIVE should come last.<br>
See <a href="https://sourceware.org/bugzilla/show_bug.cgi?id=13302" rel="noreferrer" target="_blank">https://sourceware.org/bugzilla/show_bug.cgi?id=13302</a><br>
<br>
This patch fixes above issues with the implementation similar to x86.<br>
That is, by adding two variables to record the next relocation index for<br>
R_RISCV_IRELATIVE and R_RISCV_JUMP_SLOT.<br>
<br>
A previous commit partially fixed the overwrite issue:<br>
<a href="https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=51a8a7c2e3cc0730831963651a55d23d1fae624d" rel="noreferrer" target="_blank">https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=51a8a7c2e3cc0730831963651a55d23d1fae624d</a><br>
<br>
Details below:<br>
<br>
There are three ways to access a local (non-preemptible) ifunc:<br>
(1) Through PLT + GOT, i.e. use normal function call.<br>
(2) Through GOT, i.e. use a local function pointer.<br>
(3) Through a global function pointer.<br>
<br>
For (1) and (2), a R_RISCV_IRELATIVE is created for GOT entry.<br>
For (3), a R_RISCV_IRELATIVE is created for the global pointer.<br>
The relocations overwrite issue is that, the R_RISCV_IRELATIVE created<br>
for (1) overwrite the relocations for (2) and (3).<br>
The previous commit partially fixed the overwrite issue for (2), but not<br>
for (3).<br>
