Hi all,
This patch introduces a new common function "startswith" which takes
two string arguments and returns nonzero if the first string starts
with the second. It also updates the 180 places where this logic was
written out longhand to use the new function.
I almost pushed this as obvious, but I hesitated because of its size.
Ok to commit?
Cheers,
Gary

gdb/ChangeLog:
* common/common-utils.h (startswith): New declaration.
* common/common-utils.c (startswith): New Function.
All places where this logic was used updated to use the above.

Given the obvious errors in remote.c that you just fixed, I'd say
this is going to be a very useful function.

As pointed out by Andreas... ;-)
Also, how about we rename the parameters to something like "str"
instead of "s1" and "pattern" for s2. It makes it faster, IMO,
to figure out the parameter order without having to read the
function's documentation, and therefore makes it's use a little
less error-prone.
I only skimmed through the patch, but it otherwise looks good to me.

Yeah, that's what prompted it :)

So the automated find and replace thing I wrote found and replaced
that one...

I can do that. I also found some more, with the pattern
strncmp (string, "something", sizeof ("something") -1)
so I'll update the patch to include those too.

Cool, thanks for reviewing.

Considering the lot of occurrences, IMHO the function should better be
defined as inline. Then, if the compiler can inline strncmp, the
function calls will be eliminated completely. Also, this would leave
the string comparison visible to the compiler for array-out-of-bound
checks.

Awesome!

For some reason I thought GDB didn't allow inline functions, but I
see there are quite a few so, yeah, I'll do that. Aside from
anything else it will allow the strlen calls to be eliminated for
string constants.

Hi all,
This patch introduces a new inline common function "startswith"
which takes two string arguments and returns nonzero if the first
string starts with the second. It also updates the 295 places
where this logic was written out longhand to use the new function.
Changes from the first version are:
- The function is now inline.
- The arguments got renamed to "string" and "pattern".
- I found 115 more places to use it.
Regression tested on RHEL 6.6 x86_64.
Ok to commit?
Thanks,
Gary
