| 106 | FIX ME : fix alloc interface after Ticker Number 214 is resolved, define and add union to S_fill. Then, modify postfix-fill functions to support T * with nmemb, char, and T object of any size. Finally, change alloc_internal.
|
|---|
| 107 | Or, just follow the instructions below for that.
|
|---|
| 108 |
|
|---|
| 109 | 1. Replace the current forall-block that contains defintions of S_fill and S_realloc with following:
|
|---|
| [fd54fef] | 110 | forall( T & | sized(T) ) {
|
|---|
| [ceb7db8] | 111 | union U_fill { char c; T * a; T t; };
|
|---|
| [685810e] | 112 | struct S_fill { char tag; U_fill(T) fill; };
|
|---|
| [ceb7db8] | 113 | struct S_realloc { inline T *; };
|
|---|
| 114 | }
|
|---|
| 115 |
|
|---|
| 116 | 2. Replace all current postfix-fill functions with following for updated S_fill:
|
|---|
| 117 | S_fill(T) ?`fill( char a ) { S_fill(T) ret = {'c'}; ret.fill.c = a; return ret; }
|
|---|
| 118 | S_fill(T) ?`fill( T a ) { S_fill(T) ret = {'t'}; memcpy(&ret.fill.t, &a, sizeof(T)); return ret; }
|
|---|
| 119 | S_fill(T) ?`fill( T a[], size_t nmemb ) { S_fill(T) ret = {'a', nmemb}; ret.fill.a = a; return ret; }
|
|---|
| 120 |
|
|---|
| [6c5d92f] | 121 | 3. Replace the alloc_internal$ function which is outside ttype forall-block with following function:
|
|---|
| 122 | T * alloc_internal$( void * Resize, T * Realloc, size_t Align, size_t Dim, S_fill(T) Fill) {
|
|---|
| [ceb7db8] | 123 | T * ptr = NULL;
|
|---|
| 124 | size_t size = sizeof(T);
|
|---|
| 125 | size_t copy_end = 0;

|---|

|
|---|

|
|---|

|---|

|
|---|

|
|---|
| 132 | } else {
|
|---|
| 133 | ptr = (T*) (void *) memalign( Align, Dim * size );
|
|---|
| 134 | }
|
|---|
| 135 |
|
|---|
| 136 | if(Fill.tag == 'c') {
|
|---|
| 137 | memset( (char *)ptr + copy_end, (int)Fill.fill.c, Dim * size - copy_end );
|
|---|
| 138 | } else if(Fill.tag == 't') {
|
|---|
| 139 | for ( int i = copy_end; i <= Dim * size - size ; i += size ) {
|
|---|
| 140 | memcpy( (char *)ptr + i, &Fill.fill.t, size );
|
|---|
| 141 | }
|
|---|
| 142 | } else if(Fill.tag == 'a') {
|
|---|
| 143 | memcpy( (char *)ptr + copy_end, Fill.fill.a, min(Dim * size - copy_end, size * Fill.nmemb) );
