Because PR65045 is about an ICE and this PR is about missing text in the error
messages.

It's the same piece of code causing the problem. One
needs to go to PR65045 to get the code, so this PR
is superfluous. When the ICE is fixed, then
error message should be addressed.

The piece of code is used as an example exhibiting a different problem than
PR65045.

THERE IS NO CODE THERE.
THERE IS NO CODE ATTACHED TO THIS PR.
One needs to go to PR65045 to get the code
that is causing the error message. Ergo,
this is a duplicate of PR65045.
When PR65045 is fixed. The issue with the
error message should be addressed then.

Steve,
This is a problem that has surfaced with the change to the gcc error handling.
Rainer Orth has encountered it on Solaris and it caused me to hold back on my
patch for pointer function assignment.
The patch for PR65045 is the simplest manifestation that I have found. I am
very grateful to Dominique for posting this PR because the problem has been
driving me crazy. I assumed that it was my patches that were wrong. However,
Dominique proved by going through different revisions that the December 2014
patches to error.c are the culprits.
Go easy on us both - it's getting a bit late here :-)
Cheers
Paul

Paul,
Your patch for gcc/fortran/decl.c does not apply on trunk:
if (state == COMP_BLOCK)
is now
while (state == COMP_BLOCK)

--- Comment #9 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
Even with the original patch applied to r227391, I cannot reproduce the error
that you get. On x86_64-linux-gnu, I get:
Starting program: /home/manuel/test1/226953M/build/gcc/f951

However, there is a bug indeed. The first caret line is not printed because
there was a previous buffered error at the same location that later got
cleared. However, clearing it does not reset context->last_location, which is
checked in gfc_diagnostic_starter.
This patch seems to fix it:
Index: error.c
===================================================================
--- error.c (revision 227391)
+++ error.c (working copy)
@@ -755,10 +755,13 @@ gfc_clear_pp_buffer (output_buffer *this
pretty_printer *pp = global_dc->printer;
output_buffer *tmp_buffer = pp->buffer;
pp->buffer = this_buffer;
pp_clear_output_area (pp);
pp->buffer = tmp_buffer;
+ /* We need to reset last_location, otherwise we may skip caret lines
+ when we actually give a diagnostic. */
+ global_dc->last_location = UNKNOWN_LOCATION;
}
However, it is not a very nice solution. It may happen that we give an error at
location X, then we buffer some errors, then we clear them, so we reset last
location to UNKNOWN, then we give an error at location X and we will get a
duplicated caret line. Thus, it would be better if last_location was only
updated when we actually flush the output text. However, that would require
some deeper changes, probably in diagnostic.c and in fortran/error.c to handle
both buffered and not buffered output_buffers. On the other hand, I'm not sure
the previous Fortran diagnostic machinery cared about duplicated caret lines,
thus perhaps the above is enough.
BTW, you should use %qs instead of '%s' in order to get quoting localized to
the user's language and color highlighting.

https://gcc.gnu.org/onlinedocs/gcc/Diagnostic-Message-Formatting-Options.html#Diagnostic-Message-Formatting-Options
The flag is -fdiagnostics-show-caret. The testsuite uses
-fno-diagnostics-show-caret, since we actually cannot test the caret line (the
source line with the '(1)' or '(2)' or '^' symbol below) and the info given by
-fno-diagnostics-show-caret is enough to test precise locations. The Fortran FE
testsuite uses several complicated regex to remove all possible forms of the
caret line and keep only the location information and the diagnostic text, but
I think this should not be necessary anymore since everything was converted to
the common machinery and the output with -fno-diagnostics-show-caret is already
in the desired form for the testsuite.

Even if *I* cannot reproduce this, such an error should be easy to debug: Just
put a break in diagnostic_report_diagnostic on the line that gives this message
and go up to find out what triggered this code to run. My guess is that you are
somehow triggering an ICE while reporting an ICE. It would be interesting to
understand where that strange location comes from (I guess it is
UNKNOWN_LOCATION?). And also to harden that code to not try to print a null
s.file pointer!

This bug is still present with gcc 5.2 -O3 (which does include
-foptimize-sibling-calls).
void fire_special_event(void);
void conditional_call(int cond) { if(cond) fire_special_event(); }
The above code compiles to (x86-64 gcc 5.2 -O3)
testl %edi, %edi
jne .L4
rep ret
.L4:
jmp fire_special_event
This sequence would be better:
testl %edi, %edi
jne fire_special_event
ret

Is there a linker limitation on relocations for conditional-branch targets
that aren't part of the current compilation unit? neither clang 3.7 nor icc 13
do any better than gcc. It seems to work for me when modifying the asm by hand
to jnz _Z18fire_special_eventv, and linking to a
separately-compiled definition.

Sorry for the confusion I sometime get this kind of error instead of the usual
ICE when using compilers configured with '--enable-checking=release'.

thanks, i get the below result with -fsanitize=undefined
boolmagic.c:12:16: runtime error: load of value 255, which is not a valid value
for type '_Bool'
boolmagic.c:13:15: runtime error: load of value 255, which is not a valid value
for type '_Bool'
boolmagic.c:14:15: runtime error: load of value 255, which is not a valid value
for type '_Bool'
b = 1, i = 1, j = 1
but, can i say the "-fsanitize=undefined" will _corrects_ the undefined
behaviour?
or replace the code by if/else, which works fine (lucky?)
int i; // = (u.b ? 1 : 0);
if (u.b) i = 1; else i = 0;

With the adjusted patch (IF replaced with WHILE) the ICE in PR65045 is gone and
gfortran retest cleanly, even if the error for the new test is

The patch in comment 9 restores the old (correct?) behavior without regression.

Indeed and it gets rid of the problems that I have been encountering.
Manuel,
Do you want to commit or would you like me to do it?
Cheers

--- Comment #6 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
(In reply to Martin Sebor from comment #5)

Good point. I don't know whether it is possible for the sanitizers to
distinguish between the two cases.
Pretty sure it is not possible for the warning code, since at the time of
warning we know nothing of the callers (not even if there are any callers).
