|  | // The Runtime ABI for the ARM Architecture IHI0043 section 4.1.2 The | 
|  | // floating-point helper functions to always use the base AAPCS (soft-float) | 
|  | // calling convention. | 
|  | // | 
|  | // These helper functions such as __aeabi_fadd are not explicitly called by | 
|  | // clang, instead they are generated by the ARMISelLowering when they are | 
|  | // needed; clang relies on llvm to use the base AAPCS. | 
|  | // | 
|  | // In this test we check that clang is not directly calling the __aeabi_ | 
|  | // functions. We rely on llvm to test that the base AAPCS is used for any | 
|  | // __aeabi_ function from 4.1.2 that is used. | 
|  | // | 
|  | // When compiled to an object file with -mfloat-abi=soft each function F | 
|  | // below should result in a call to __aeabi_F. If clang is changed to call any | 
|  | // of these functions directly the test will need to be altered to check that | 
|  | // arm_aapcscc is used. | 
|  | // | 
|  | // Note that it is only the functions in 4.1.2 that must use the base AAPCS, | 
|  | // other runtime functions such as the _Complex helper routines are not covered. |
