[Bug gas/25264] New: RISC-V option norvc: linker complains "14 bytes required for alignment to 16-byte boundary, but only 12 present"

Bug ID: 25264
   Summary: RISC-V option norvc: linker complains "14 bytes
required for alignment to 16-byte boundary, but only
12 present"
   Product: binutils
   Version: 2.34 (HEAD)
Status: UNCONFIRMED
  Severity: normal
  Priority: P2
 Component: gas
  Assignee: unassigned at sourceware dot org

failing test case

When I switch back and forth between '.option rvc' and '.option norvc', the
alignment mechanism seems to break. When linking I get this failure:

riscv64-unknown-elf-ld: lotsaregs.o(.text+0x2): 14 bytes required for alignment
to 16-byte boundary, but only 12 present
riscv64-unknown-elf-ld: can't relax section: bad value
make: *** [lotsaregs.elf] Error 1


See attached testcase. This was run using binutils 2.33.50.20191209 (latest
master git bac7c5cf) but also seen in a months-old release. Built today using
crosstools-ng 1.24.0.

(The error message comes from ld but I suspect the problem originates in as, so
I'm filing this under as.)

In another instance (no testcase, sorry) a .balign 4 failed to achieve the
intended alignment, giving no error message but leaving the next instruction
only 2-byte aligned.
