Test Failues with libffi

[Brent L. Bates]

     I'm trying to install the lastest version of libffi (3.0.9) on a SGI
running IRIX 6.5.22f and the MIPS Pro 7.4.4m compilers.  The test report
says I have 15 `unexpected failures'.  5 tests are run 3 times with different
compiler optimization options, so I really have only 5 failures.
     One of the failures makes no sense at all.  It says the output does not
match what is expected, but it does match.  Here is the output:

Running /usr/local/src/libffi/libffi-3.0.9/testsuite/libffi.call/call.exp ...
FAIL: libffi.call/cls_dbls_struct.c -O0 output pattern test, is 1.0 2.0
1.0 2.0, should match 1.0 2.0?
1.0 2.0?

     The only thing I can think of is there is some kind of carriage
return/line feed mismatch as the numbers match.

     The next 2 failures I don't know what to make of.  Here is their output:

FAIL: libffi.call/cls_double_va.c -O0 output pattern test, is 0.0
res: 4
7.0
res: 4, should match 7.0?
res: 4?
7.0?
res: 4
FAIL: libffi.call/cls_longdouble_va.c -O0 output pattern test, is 0.0
res: 4
7.0
res: 4, should match 7.0?
res: 4?
7.0?
res: 4

     The final 2 failures are because the test insists on using the C
compiler instead of the C++ comiler on C++ source files.  Here are the errors:

Running /usr/local/src/libffi/libffi-3.0.9/testsuite/libffi.special/special.exp ...

     I had to make changes to 2 files to get rid of some compiler
errors/warnings.  These are the changes:

diff -bwir libffi-3.0.9.org/testsuite/libffi.call/ffitest.h libffi-3.0.9/testsuite/libffi.call/ffitest.h
18c18
< #define CHECK(x) !(x) ? abort() : 0
---
> #define CHECK(x) if( !(x) ) { abort(); }


diff -bwir libffi-3.0.9.org/testsuite/libffi.call/nested_struct9.c libffi-3.0.9/testsuite/libffi.call/nested_struct9.c
33c33
<   result.y = b2.b + b3.x.b + b4.e;
---
>   result.y = (unsigned char)(b2.b + b3.x.b + b4.e);

      Any help in resolving these issues would be greatly appreciated.  Thanks.
