2017-09-04PR82045: Avoid passing machine modes through "..."Richard Sandiford1-4/+4
PR82045 is about a bootstrap failure on sparc-sun-solaris2.11. The problem was that we were passing the new machine_mode wrapper classes through "..." to emit_library_call(_value), which then read them back as ints instead. The simplest fix seemed to be replace "..." with an array of rtx_mode_ts, then provide wrappers for the common cases. This bulks out rtl.h a bit, but it does make things a bit more typesafe. 2017-09-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR bootstrap/82045 * rtl.h (emit_library_call_value_1): Declare.
