For instance on IA-32 architecture an 26 atomic like this can be inlined 27 @code 28 static int s = 0; 29 #pragma omp atomic 30 s++; 31 @endcode 32 using the single instruction: `lock; incl s` 33 34 However the runtime does provide entrypoints for these operations to support 35 compilers that choose not to inline them. (For instance, 36 `__kmpc_atomic_fixed4_add` could be used to perform the increment above.) 37 38 The names of the functions are encoded by using the data type name and the 39 operation name, as in these tables. 40 41 Data Type | Data type encoding 42 -----------|--------------- 43 int8_t | `fixed1` 44 uint8_t | `fixed1u` 45 int16_t | `fixed2` 46 uint16_t | `fixed2u` 47 int32_t | `fixed4` 48 uint32_t | `fixed4u` 49 int32_t | `fixed8` 50 uint32_t | `fixed8u` 51 float | `float4` 52 double | `float8` 53 float 10 (8087 eighty bit float) | `float10` 54 complex<float> | `cmplx4` 55 complex<double> | `cmplx8` 56 complex<float10> | `cmplx10` 57 <br> 58 59 Operation | Operation encoding 60 ----------|------------------- 61 + | add 62 - | sub 63 \* | mul 64 / | div 65 & | andb 66 << | shl 67 \>\> | shr 68 \| | orb 69 ^ | xor 70 && | andl 71 \|\| | orl 72 maximum | max 73 minimum | min 74 .eqv. | eqv 75 .neqv. | neqv 76 77 <br> 78 For non-commutative operations, `_rev` can also be added for the reversed 79 operation. For the functions that capture the result, the suffix `_cpt` is 80 added. 81 82 Update Functions 83 ================ 84 The general form of an atomic function that just performs an update (without a 85 `capture`) 86 @code 87 void __kmpc_atomic_<datatype>_<operation>( ident_t *id_ref, int gtid, TYPE * 88 lhs, TYPE rhs ); 89 @endcode 90 @param ident_t a pointer to source location 91 @param gtid the global thread id 92 @param lhs a pointer to the left operand 93 @param rhs the right operand 94 95 `capture` functions 96 =================== 97 The capture functions perform an atomic update and return a result, which is 98 either the value before the capture, or that after. They take an additional 99 argument to determine which result is returned. 100 Their general form is therefore 101 @code 102 TYPE __kmpc_atomic_<datatype>_<operation>_cpt( ident_t *id_ref, int gtid, TYPE * 103 lhs, TYPE rhs, int flag ); 104 @endcode 105 @param ident_t a pointer to source location 106 @param gtid the global thread id 107 @param lhs a pointer to the left operand 108 @param rhs the right operand 109 @param flag one if the result is to be captured *after* the operation, zero if 110 captured *before*. 111 112 The one set of exceptions to this is the `complex<float>` type where the value 113 is not returned, rather an extra argument pointer is passed. 114 115 They look like 116 @code 117 void __kmpc_atomic_cmplx4_<op>_cpt( ident_t *id_ref, int gtid, kmp_cmplx32 * 118 lhs, kmp_cmplx32 rhs, kmp_cmplx32 * out, int flag ); 119 @endcode 120 121 Read and Write Operations 122 ========================= 123 The OpenMP<sup>*</sup> standard now supports atomic operations that simply 124 ensure that the value is read or written atomically, with no modification 125 performed. In many cases on IA-32 architecture these operations can be inlined 126 since the architecture guarantees that no tearing occurs on aligned objects 127 accessed with a single memory operation of up to 64 bits in size. 128 129 The general form of the read operations is 130 @code 131 TYPE __kmpc_atomic_<type>_rd ( ident_t *id_ref, int gtid, TYPE * loc ); 132 @endcode 133 134 For the write operations the form is 135 @code 136 void __kmpc_atomic_<type>_wr ( ident_t *id_ref, int gtid, TYPE * lhs, TYPE rhs 137 ); 138 @endcode 139 140 Full list of functions 141 ====================== 142 This leads to the generation of 376 atomic functions, as follows. 143 144 Functions for integers 145 --------------------- 146 There are versions here for integers of size 1,2,4 and 8 bytes both signed and 147
