Description Alex Fan archtester 2021-11-20 11:43:06 UTC
reproducible on both Sifive Unmatched board and qemu riscv64 environment.

 * QA Notice: The following files contain runtime text relocations                                                  
 *  Text relocations force the dynamic linker to perform extra
 *  work at startup, waste system resources, and may pose a security
 *  risk.  On some architectures, the code may not even function
 *  properly, if at all.                                  
 *  For more information, see:                                                                                      
 *

Comment 3 Alex Fan archtester 2021-11-20 12:22:55 UTC
This could be fixed temporally by append-ldflags "-Wl,-z,notext like 32 bits arches, but the case for riscv64 is different from bug #773226. According to upstream, ocaml supports generating PIC on riscv64. 

> scanelf -qT str.cmxs
...
  str.cmxs: (memory/data?) [r_offset=0x10F58] r_type=3 in (optimized out: previous camlStr__frametable) [closest_prev_sym=0xEED8]
  str.cmxs: (memory/data?) [r_offset=0x10F68] r_type=3 in (optimized out: previous camlStr__frametable) [closest_prev_sym=0xEED8]
  str.cmxs: (memory/data?) [r_offset=0x10F80] r_type=3 in (optimized out: previous camlStr__frametable) [closest_prev_sym=0xEED8]
...

r_type=3 is R_RISCV_RELATIVE

Also, previously (portage tree is on around 2021.10.09), many tests failed with "warning: creating DT_TEXTREL in a PIE". But now no test failures appear with current portage tree.
