- Subject: [PATCH] RISC-V: Add %got_pcrel_hi operator
This operator allows compilers to expand the "la" pseduo-instruction and
potentially split up the two instructions.
gas/
* config/tc-riscv.c (percent_op_utype): Add entry for a new
%got_pcrel_hi operator.
* testsuite/gas/riscv/no-relax-reloc.d: Update for new
%got_pcrel_hi operator test.
* testsuite/gas/riscv/no-relax-reloc.s: Add a %got_pcrel_hi
operator test.
* testsuite/gas/riscv/relax-reloc.d: Update for new
%got_pcrel_hi operator test.
* testsuite/gas/riscv/relax-reloc.s: Add a %got_pcrel_hi
operator test.
