/usr/src/gcc-4.4.3/gcc/testsuite/{gcc.c-torture | gcc.dg | c-c++common |
somethingElse}
I have all the "stuff" to run, I just don't yet know how.
AND I have to be able to move the code to a simulator which uses command
line inputs so that is easy. My problem (not good at Makefile or scrpts)
is that I need to get it to run a perl script in the code that (if
compile is successful) will run a perl script to strip out stuff from the
.elf file and run them into the simulator that will return 1 or 0
(0=PASS; else FAIL)

so I would have
make check-gcc.c-torture RUNTESTFLAGS="execute.expother-options"
make check-gcc.dg RUNTESTFLAGS="execute.expother-options"
make check-gcc.c-c++common RUNTESTFLAGS="execute.expother-options"

Yes, I saw those.

I've got to work on the testsuite and make sure I have coverage for the
list which I replaced and added my thoughts.
I gotta present my ideas on this stuff today.
1. Recursive function calls (to test 'call stack'-related
functionality)
There are tests for this in the testsuite, but probably will
require modification.
2. Pointers
(a) Array-pointer interchangeability
There are tests for this in the testsuite, but may require
modification.
(b) Type casting
There are tests for this in the testsuite, but may
require modification.
(c) Function arguments
There are tests for this in the testsuite, but may
require modification.
3. typedef
There are tests for this in the testsuite, but may require
modification.
4. multi-dimensional arrays
There are tests for this in the testsuite, but probably will
require modification because of space constraints.
5. Statements:
(a) switch (including nested switch)
There are tests for this in the testsuite, but probably
will require modification because of space constraints.
(b) do/while
There are tests for this in the testsuite, and may not
require modification.
(c) goto, break, continue
There are tests for this in the testsuite, but may not
require modification.
(d) for (includes tests for exclusion of the initialization,
test, and update parts of the for statement)
There are tests for this in the testsuite, but probably
will require modification because of space constraints.
6. Structures (accessing members of structures, operations on
members, pointers to structures)
There are tests for this in the testsuite, but probably will
require modification.
7. Returning Arrays (as static array or pointer-based function
argument)
There are tests for this in the testsuite, but probably will
require modification because of space constraints.
8. Preprocessor
(a) Macro definition and expansion for simple values and
function-like macros)
There are tests for this in the testsuite, but may not
require modification.
(b) Variadic Macros
There are tests for this in the testsuite, but may not
require modification.
(c) Conditional inclusion
There are tests for this in the testsuite, and may not
require modification.
9. Variable-length argument lists
There are tests for this in the testsuite, but probably will
require modification because of space constraints.
10. Special keywords (const, volatile, extern, inline, sizeof,
static)
There are tests for this in the testsuite, and may not
require modification.
11. Operators:
(a) Arithmetic (+, -, *, /, %)
This will be where the work needs to be done.
1) no math library
2) no available multiply nor divide instruction, so a
library is needed for those functions
3) no divide, so '%' will require a "library" function
(b) Boolean (!, &&, ||)
There are tests for this in the testsuite, and may not
require modification.
(c) Bitwise (~, &, |, ^, >>, <<)
There are tests for this in the testsuite, and may not
require modification.
(d) Referencing and dereferencing (related to pointer
manipulation)
There are tests for this in the testsuite, but probably
will require modification because of space constraints.
(e) Conditional evaluation
There are tests for this in the testsuite, and may not
require modification.
(f) Member selection (for structures, unions, pointer-based, etc)
There are tests for this in the testsuite, but may
require modification.
12. Nests:
(a) Loops
There are tests for this in the testsuite, and may not
require modification.
(b) Function calls
There are tests for this in the testsuite, but may
require modification.
(c) Preprocessor Macros
There are tests for this in the testsuite, and may not
require modification.
(d) Structures
There are tests for this in the testsuite, but may
require modification.
13. Interrupt handling
Work will need to be done here but may not be possible with
just the simulator because something controlled exteranlly needs to trip
the interrupt.

Not a problem. You have actually been rather helpful.

2 problems have been found:
#1 what was given:
configure --target=xxx
it shoud have been
configure --target=xxx-elf
#2 configure (and then make) was especting texinfo4.4 to 4.9, but I had
texinfo4.13 and it just could not see it and died.
Once that was OK, I was able to compile binutils. Then I hung up on GCC
missing some variables that are supposed to come from mpfr, Should there
be a #include in the gcc/builtin.c file? I didn't see any #include that
I would expect that would have
#define BUILT_IN_J0 __imp__mpfr_j0
and then where does mpfr come in? The guy who compiled it before me
would know...When he gets in later today, maybe he'll answer.
