/* Walk the tree X, and record accesses to variables. If X is written by the
|
|
|
|
|
parent tree, WRITER is the parent.
|
|
|
|
|
We store accesses in one of the two lists: PBEFORE_SP, and PNO_SP. If this
|
|
|
|
|
expression or its only operand forces a sequence point, then everything up
|
|
|
|
|
to the sequence point is stored in PBEFORE_SP. Everything else gets stored
|
|
|
|
|
in PNO_SP.
|
|
|
|
|
Once we return, we will have emitted warnings if any subexpression before
|
|
|
|
|
such a sequence point could be undefined. On a higher level, however, the
|
|
|
|
|
sequence point may not be relevant, and we'll merge the two lists.
|
|
|
|
|
|
|
|
|
|
Example: (b++, a) + b;
|
|
|
|
|
The call that processes the COMPOUND_EXPR will store the increment of B
|
|
|
|
|
in PBEFORE_SP, and the use of A in PNO_SP. The higher-level call that
|
|
|
|
|
processes the PLUS_EXPR will need to merge the two lists so that
|
|
|
|
|
eventually, all accesses end up on the same list (and we'll warn about the
|
|
|
|
|
unordered subexpressions b++ and b.
|
|
|
|
|
|
|
|
|
|
A note on merging. If we modify the former example so that our expression
|
|
|
|
|
becomes
|
|
|
|
|
(b++, b) + a
|
|
|
|
|
care must be taken not simply to add all three expressions into the final
|
|
|
|
|
PNO_SP list. The function merge_tlist takes care of that by merging the
|
|
|
|
|
before-SP list of the COMPOUND_EXPR into its after-SP list in a special
|
|
|
|
|
way, so that no more than one access to B is recorded. */

re PR c/461 (non-lvalue arrays)
* c-common.c (c_expand_expr_stmt): Apply default conversions to
non-lvalue arrays if C99.
* c-typeck.c (default_conversion): Split out code handling
array-to-pointer and function-to-pointer conversions into a
separate default_function_array_conversion function.
(default_function_array_conversion): New function. Keep track of
whether any NON_LVALUE_EXPRs were stripped. Return non-lvalue
arrays unchanged outside C99 mode instead of giving an error for
them.
(build_component_ref): Use pedantic_non_lvalue when handling
COMPOUND_EXPR. Don't handle COND_EXPR specially.
(convert_arguments): Use default_function_array_conversion.
(build_unary_op): For ADDR_EXPR, take a flag indicating whether
non-lvalues are OK.
(unary_complex_lvalue): Likewise.
(internal_build_compound_expr): Use
default_function_array_conversion. Apply default conversions to
function in compound expression.
(build_c_cast, build_modify_expr, digest_init, build_asm_stmt):
Use default_function_array_conversion.
* doc/extend.texi: Update documentation of subscripting non-lvalue
arrays.

This is only interesting if the constant is the wider arg.

Also, it is not safe if the constant is unsigned and the

variable arg is signed, since in this case the variable

|
|
would be sign-extended and then regarded as unsigned.
|

Our technique fails in this case because the lowest/highest

possible unsigned results don't follow naturally from the
|
|
|
|
|
lowest/highest possible values of the variable operand.
|
|

|
For just EQ_EXPR and NE_EXPR there is another technique that
|
|
|
|
|
could be used: see if the constant can be faithfully represented
|
|
|
|
|
in the other operand's type, by truncating it and reextending it
|
|
|
|
|
and see if that preserves the constant's value. */

/* Unfortunately, there is no canonical form of a pointer type.
|
|
|
|
|
In particular, if we have `typedef int I', then `int *', and
|
|
|
|
|
`I *' are different types. So, we have to pick a canonical
|
|
|
|
|
representative. We do this below.

|
|
|
|
Technically, this approach is actually more conservative that
|
|
|
|
|
it needs to be. In particular, `const int *' and `int *'

should be in different alias sets, according to the C and C++
|
1999-08-20 23:57:38 +02:00
|
|
|
|
standard, since their types are not the same, and so,
|
|
|
|
|
technically, an `int **' and `const int **' cannot point at
|
|
|
|
|
the same thing.
|
|
|
|
|
|
|
|
|
|
But, the standard is wrong. In particular, this code is
|
|
|
|
|
legal C++:
|
|
|
|
|
|
|
|
|
|
int *ip;
|
|
|
|
|
int **ipp = &ip;
|
2001-05-21 18:06:37 +02:00
|
|
|
|
const int* const* cipp = &ipp;
|
1999-08-20 23:57:38 +02:00
|
|
|
|
|
|
|
|
|
And, it doesn't make sense for that to be legal unless you
|
|
|
|
|
can dereference IPP and CIPP. So, we ignore cv-qualifiers on
|
|
|
|
|
the pointed-to types. This issue has been reported to the
|
|
|
|
|
C++ committee. */

If we requested a pointer to a vector, build up the pointers that

we stripped off while looking for the inner type. Similarly for
|
|
|
|
|
return values from functions.

The argument "type" is the top of the chain, and "bottom" is the

|
|
|
|
new type which we will point to. */
