Re: Avoid explicit use of machine modes (11/n) conversions

[Richard Earnshaw <rearnsha at arm dot com>]

It was a jumbo patch, so I'll forgive you this one little bug...

Unfortunately, it breaks the bootstrap on anything that uses soft-float 
libraries (eg arm-netbsdelf).

According to opcodes.h the convert arrays are in the form [dest][source], 
so the following initializer is inverted:

+static void
+init_intraclass_conv_libfuncs (convert_optab tab, const char *opname,
...
+	tab->handlers[widening ? nmode : wmode]
+	             [widening ? wmode : nmode].libfunc
+	  = init_one_libfunc (ggc_alloc_string (libfunc_name,

It should of course be

+	tab->handlers[widening ? wmode : nmode]
+	             [widening ? nmode : wmode].libfunc
+	  = init_one_libfunc (ggc_alloc_string (libfunc_name,

Since when widening the destination is the wider mode.

R.

	indicees for floating-point conversersion libcalls.
