Change

The following text is added at the end of the "-W{error|remark|suppress|warn} number[, number...]" section.

As shown in the Output window and in Help, error codes sometimes begin with a leading zero (for example, cc0025). If you try to suppress error codes with -W{error|remark|suppress|warn} or #pragma diag() and supply the code with a leading zero, it will not work. This is because the compiler reads the number as an octal value, and will suppress a different warning or error.

Change

The prototype of "__builtin_compose_64" in the section "Composition and Decomposition" is incorrect. Change from:

long long int __builtin_compose_64(int hi, int lo);
Change to:
long long int __builtin_compose_64(int lo, int hi);

Change:

const char __argv_string[] = "-in x.gif -out y.jpeg";

To:
extern const char __argv_string[] = "-in x.gif -out y.jpeg";

Change

The example for argv and argc should change from:

const char __argv_string[] = "-in x.gif –out y.jpeg";

Change to:
const char __argv_string[] = "prog_name -in x.gif –out y.jpeg";

This change is needed because, typically, argv[0] is the command that has just been executed.

Change

A series of heap related changes are needed.

On page 1-280, change from:

The default heap, seg_heap, is always 0 and the primary heap IDs of user-defined heaps are 1 with any additional user-defined heaps being 2, 3, and so on, with each heap index being an increment of one from the previous heap index.

Change to:
The default heap, seg_heap, is always 0 and the alternate heap is always 1 with any additional user-defined heaps being 2, 3, and so on, with each heap index being an increment of one from the previous heap index.

On page 1-286, in the code comments, correct the spelling from Initailiase to Initialize.

On page 3-215, add the following note at the end of the description:
You should not initialize a heap at runtime with the same id as a statically defined heap, including the default heap and alternate heap (with ids 0 and 1, respectively) if they are present.

Change

Replace the following sentence in the fir_interp section:

Each filter should have its own delay line which is a vector of type float and whose length is equal to the number of coefficients.
with
Each filter should have its own delay line which is a vector of type float and whose length is equal to the number of coefficients per polyphase filter.
In the Example section for fir_interp replace the following line:
float delay[NCOEFFS];
with:
float delay[NCOEFFS/NPOLY];
In addition, change the code in this section from
/* Initialize the delay line */
for (i = 0; i < NCOEFFS; i++)
      delay[i] = 0;
to:
/* Initialize the delay line */
for (i = 0; i < NCOEFFS/NPOLY; i++)
      delay[i] = 0;

Change

The reference page for fscanf does not describe all the length modifiers that are supported by the function. Under the heading "Description", do the following to correct the problem:

  • In the 5th paragraph (The length modifier can be used to specify ...), remove the character sequence e, f, g, from the 2nd sentence (The length modifiers should only precede ...).
  • Following the 5th paragraph (The length modifier can be used to specify the size of the ...) Table 3-29. (Length Modifier for fscanf) documents the length modifiers h and l and ll and L. Replace this table with the corresponding table in the Blackfin manual (on page 3-163).
  • Insert the following paragraph immediately after the above-mentioned table:
    Note that the hh, j, t, and z size specifiers are defined in the C99 (ISO/IEC 9899:1999) standard.
  • The following symbols in the new paragraph should be in Letter Gothic font: hh, j, t, z

Change

Change the description of the heap_switch() from:

If the heap_index is the current heap then heap_index is returned, otherwise a value of -1 is returned.

Change to:
If the current heap was previously set then the index of the previous heap is returned, otherwise -1 is returned.

Change

The example for heap_switch is not correct. Change from:

int heap1[256]; /* memory for heap 1*/
int main()
{
  char *buf;
  heap_install(heap1, sizeof(heap1), 1);
  heap_switch(1); /* make heap 1 the default heap */
Change to:
int heap2[256]; /* memory for heap 2*/
int main()
{
  char *buf;
  heap_install(heap2, sizeof(heap2), 2);
  heap_switch(2); /* make heap 2 the default heap */

Change

Change the first parameter in the reference page for qsort from void base to void *base (insert the asterisk).
