Subject: gas/write: extend fx_pcrel_adjust to 16 bits
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=refs%2Fheads%2Ffx_pcrel_adjust;p=binutils-gdb.git

gas/write: extend fx_pcrel_adjust to 16 bits

PowerPC code stores operand index into fx_pcrel_adjust field of fix
struct. Once count of PowerPC operands exceeds an 8-bit integer, the
code won't be able to store operand index anymore.
This patch extends the aforementioned field to 16 bits, exactly like
the ppc_opindex_t type; the missing 8 bits are taken from the fx_unused
field.
