// 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.
