Subject: Re: New: sprint_value prints small constants in hex
on 64-bit targets
Hi
>sprint_value() prints small constants (for example, operands that are out of
>range) in hex on targets where sizeof (valueT) > sizeof (long). This leads to

>foo.s:2: Error: operand out of range (0000000000000020 not between 0 and 31)

How about this patch to fix the problem ? It creates a new function
called as_warn_value_out_of_range() which is responsible for printing a
reasonable warning message. It checks the range of the values and uses
decimals if they are small enough, otherwise it used hexadecimals.
Either way, it is consistent about the format it uses to print the
numbers. The patch also includes a version of the function which
generates an error instead of a warning, and it also has the benefit of
eliminating a small amount of duplicated code found in several ports.
Cheers

2004-05-05 Nick Clifton <address@hidden>
* messages (as_internal_value_out_of_range): Print a message about
a value being out of range. Be consistent about whether the
values are printed in decimal or hexadecimal.
(as_warn_value_out_of_range): Generate a warning message about an
out of range value.
(as_bad_value_out_of_range): Generate an error message about an
out of range value.
* as.h: Prototype the new functions.
* config/tc-alpha.c (insert_operand): Use new function.
* config/tc-arc.c (arc_insert_operand): Likewise.
* config/tc-mn10200.c (mn10200_insert_operand): Likewise.
* config/tc-mn10300.c (mn10300_insert_operand): Likewise.
* config/tc-ppc.c (ppc_insert_operand): Likewise.
* config/tc-s390.c (s390_insert_operand): Likewise.
* config/tc-v850.c (v850_insert_operand): Likewise.
