            Bug ID: 58630
           Summary: [4.9 Regression] Revision 203171 breaks several MS-ABI
                    tests
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dominiq at lps dot ens.fr

                    ktietz at gcc dot gnu.org
            Target: i?86-*-* x86_64-*-*

Revision 203171 breaks several MS-ABI tests:

(see http://gcc.gnu.org/ml/gcc-regression/2013-10/msg00026.html or
http://gcc.gnu.org/ml/gcc-testresults/2013-10/msg00388.html ).

The failure for gcc.target/i386/pr9771-1.c is

[macbook] f90/bug% gfc -O2 -fomit-frame-pointer -ffixed-ebp
/opt/gcc/work/gcc/testsuite/gcc.target/i386/pr9771-1.c -m32
/opt/gcc/work/gcc/testsuite/gcc.target/i386/pr9771-1.c: In function 'test':
/opt/gcc/work/gcc/testsuite/gcc.target/i386/pr9771-1.c:46:1: error: bp cannot
be used in asm here
 }

and the others are of the kind

sorry, unimplemented: ms_abi attribute requires -maccumulate-outgoing-args or
subtarget optimization implying it

Notes:

(1) Compiling the failing gcc.target/i386/pr4* and
gcc.target/x86_64/abi/callabi/func-indirect-2a.c gives an ICE:

/opt/gcc/work/gcc/testsuite/gcc.target/i386/pr43662.c:20:9: internal compiler
error: in expand_call, at calls.c:3153

or

internal compiler error: in expand_call, at calls.c:3453

for the others.

(2) Some tests are restricted to Linux but can be run on Darwin without
failure.

(3) The following patch fixes the failures related to
-maccumulate-outgoing-args

Sorry still present at revision 205008: see
http://gcc.gnu.org/ml/gcc-testresults/2013-11/msg01438.html or
http://gcc.gnu.org/ml/gcc-testresults/2013-11/msg01440.html (r204983).

The difference in behavior may depend on the configure options, but I did not
find what could be relevant.

            Bug ID: 59513
           Summary: Fortran runtime error: Sequential READ or WRITE not
                    allowed after EOF marker, possibly use REWIND or
                    BACKSPACE
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libfortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: aruopp at gmx dot de

Compiling xfoil, a known fortran code for airfoils works perfectly. Execution
of xfoil creates an error, unfortunetly.
Problem during execution of xfoil:
At line 652 of file ../src/iopol.f (unit = 9, file = 'polarfile_1.dat')
Fortran runtime error: Sequential READ or WRITE not allowed after EOF marker,
possibly use REWIND or BACKSPACE

Source code can be found for example in:
http://code.google.com/p/mjl-xfoil/source/browse/branches/osx/src/iopol.f?r=5

The compiler has problems with:
...
DO 40 IA = IA1, IA2
WRITE(LU,LINEF)
& (CPOL(IA,IPOL(KP)), KP=1, NIPOL),
& ((CPOLSD(IA,IS,JPOL(KP)), IS=1, 2*NBL), KP=1, NJPOL)
40 CONTINUE
...
?
Bug in compiler or bug in source code.
Source code works with gcc-4.3.6

Thanks in advance
