creduced object
This error occurs with lld at symbol resolution, but it works fine with bfd or
gold. I have attached 2 set of sources, normal and creduced.
1. Noraml
- Command: ld.lld -shared sha1-armv8.o -o sha1-armv8.lld.so
- Output: ld.lld: error: sha1-armv8.S:1202: can't create dynamic
relocation R_AARCH64_PREL64 against symbol 'OPENSSL_armcap_P' defined in
sha1-armv8.o
- Original sha1-armv8.orig.S from which sha1-armv8.o is generated.
2. Creduced
- Command: ld.lld -shared sha1-armv8.creduced.o -o sha1-armv8.lld.so
- Output: ld.lld: error: sha1-armv8.creduced.o:(.text+0x0): can't create
dynamic relocation R_AARCH64_PREL64 against symbol 'a' defined in
sha1-armv8.creduced.o
- Creduced sha1-armv8.S from which sha1-armv8.creduced.o is generated.
It seems that the root cause of this error is that the symbol,
R_AARCH64_PREL64, is evaluated as preemptible. I am not sure this is a subtle
corner case of symbol resolution or intentional.</pre>
