Hi!
The following patch unbreaks riscv bootstrap, where it previously failed
on -Werror=format-diag warning promoted to error.
Ok for trunk?
Or shall it say e.g.
"%<-march=%s%>: %<zfinx%> extension conflicts with %<f>"
?
Or say if the current condition is true, do
const char *ext = "zfinx";
if (subset_list->lookup ("zdinx"))
ext = "zdinx";
else if (subset_list->lookup ("zhinx"))
ext = "zhinx";
else if (subset_list->lookup ("zhinxmin"))
ext = "zhinxmin";
and
"%<-march=%s%>: %qs extension conflicts with %<f>", arch, ext
? Or do similar check for which extension to print against it,
const char *ext = "zfinx";
const char *ext2 = "f";
if (subset_list->lookup ("zdinx"))
{
ext = "zdinx";
if (subset_list->lookup ("d"))
ext2 = "d";
}
else if (subset_list->lookup ("zhinx"))
{
ext = "zhinx";
if (subset_list->lookup ("zfh"))
ext2 = "zfh";
}
else if (subset_list->lookup ("zhinxmin"))
{
ext = "zhinxmin";
if (subset_list->lookup ("zfhmin"))
ext2 = "zfhmin";
}
"%<-march=%s%>: %qs extension conflicts with %qs", arch, ext, ext2
?

Reword diagnostics about zfinx conflict with f, formatting fixes.
* gcc.target/riscv/arch-19.c: Expect a different message about zfinx
vs. f conflict.
