From: Wu Zhou Date: Fri, 24 Feb 2006 07:26:10 +0000 (+0000) Subject: * f-exp.y: Symbol '%' is not used as the modulus operator in X-Git-Tag: gdb-csl-20060226-branchpoint~18 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2a5e440cb420e37baa7e716febb0d48586e8f44b;p=platform%2Fupstream%2Fbinutils.git * f-exp.y: Symbol '%' is not used as the modulus operator in Fortran. Delete this from Fortran expression. It is now used by Fortran 90 and later to access the member of derived type. Add this into Fortran expression. * f-valprint.c (f_val_print): Add code to handle TYPE_CODE_STRUCT. Print each elements in the derived type. * f-typeprint.c (print_equivalent_f77_float_type): Add a parameter level into the function definition to do indented printing. And call fprintfi_filtered instead to do indented printing. (f_type_print_base): Replace fprintf_filtered with the indented version (fprintfi_filtered). (f_type_print_base): Call indented print_equivalent_f77_float_type. (f_type_print_base): Add code to handle TYPE_CODE_STRUCT. Print the definition of the derived type. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index f26f680..3c14515 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,20 @@ +2006-02-24 Wu Zhou + + * f-exp.y: Symbol '%' is not used as the modulus operator in + Fortran.
