In order to facilitate the fine-tuning of how `libatomic_i.h' and `host-config.h' headers are used by different atomic functions, we define distinct identifier macros for each file which, in implementing atomic operations, imports these headers. The idea is that different parts of these headers could then be conditionally defined depending on the macros set by the file that `#include'd them. Given how it is possible that some file names are generic enough that using them as-is for macro names (e.g. flag.c -> FLAG) may potentially lead to name clashes with other macros, all file names first have LAT_ prepended to them such that, for example, flag.c is assigned the LAT_FLAG macro. Libatomic/ChangeLog: * cas_n.c (LAT_CAS_N): New. * exch_n.c (LAT_EXCH_N): Likewise. * fadd_n.c (LAT_FADD_N): Likewise. * fand_n.c (LAT_FAND_N): Likewise. * fence.c (LAT_FENCE): Likewise. * fenv.c (LAT_FENV): Likewise. * fior_n.c (LAT_FIOR_N): Likewise. * flag.c (LAT_FLAG): Likewise. * fnand_n.c (LAT_FNAND_N): Likewise. * fop_n.c (LAT_FOP_N): Likewise * fsub_n.c (LAT_FSUB_N): Likewise. * fxor_n.c (LAT_FXOR_N): Likewise. * gcas.c (LAT_GCAS): Likewise. * gexch.c (LAT_GEXCH): Likewise. * glfree.c (LAT_GLFREE): Likewise. * gload.c (LAT_GLOAD): Likewise. * gstore.c (LAT_GSTORE): Likewise. * load_n.c (LAT_LOAD_N): Likewise. * store_n.c (LAT_STORE_N): Likewise. * tas_n.c (LAT_TAS_N): Likewise.
