Re: How to add an additional option to dg-compile and dg-run

[Thomas Koenig]

Hi Andrew,

Any other possibilites?

Yes you could add it into the list of Torture options that
gfortran-dg-runtest uses.
Something like:
```
diff --git a/gcc/testsuite/lib/gfortran-dg.exp
b/gcc/testsuite/lib/gfortran-dg.exp
index fcba95dc396..0589d507382 100644
--- a/gcc/testsuite/lib/gfortran-dg.exp
+++ b/gcc/testsuite/lib/gfortran-dg.exp
@@ -153,6 +153,12 @@ proc gfortran-dg-runtest { testcases flags
default-extra-flags } {
         } else {
             set option_list [list { -O } ]
         }
+       set old_option_list  $option_list
+       set option_list {}
+       foreach option $option_list {
+         lappend option_list $option
+         lappend option_list "$option -funsigned"
+       }

         set nshort [file tail [file dirname $test]]/[file tail $test]
         list-module-names $test
```
should work but I am not 100% I got the TCL syntax correct.

I tried this (well, a variant) but that also appended the -funsigned
option to the C compiler, where it again caused compilation errors.

Best regards
