[sv-bc] RE: Mantis 1523 conditional operator with arrays

Hi Shalom.

For the first issue, the proposal was modified as follows:

Regardless of the result of the cond_predicate, the first and second expressions are extended to the same width, as described in 11.6.1 and 11.8.2.

For the second issue the phrasing is:

For integral expressions, if the cond_predicate evaluates to an ambiguous value and the expressions are not logically equivalent, and their results shall be combined bit by bit using Table 11-20 to calculate the final result unless either the first or second expression is real, in which case the result shall be 0.

And that seems to make sense-it's covering the case when there is one integral and one real expression. What's the problem?

Hi,

In the current LRM, the sentence that says for integral operands, "the first and second expressions are extended to the same width" is not dependent on the value of cond_predicate. As you have reformulated it, that sentence applies only when cond_predicate is ambiguous and the expressions are not logically equivalent.

Also, by adding "For integral expressions," then the phrase "unless either the first or second expression is real, in which case the result shall be 0," should be deleted.

Regards,
Shalom
