The ELF psABI-s are quite clear here: On 32-bit the underlying data type is 12 bytes long (with 2 bytes of trailing padding), while on 64-bit it is 16 bytes long (with 6 bytes of padding). Make s_space() capable of handling 'x' (and 'p') type floating point being other than 12 bytes wide (also adjusting documentation). This requires duplicating the definition of X_PRECISION in the target speciifc header; the compiler would complain if this was out of sync with config/atof-ieee.c. Note that for now padding space doesn't get separated from actual storage, which means that things will work correctly only for little- endian cases, and which also means that by specifying large enough numbers padding space can be set to non-zero. Since the logic is needed for a single little-endian architecture only for now, I'm hoping that this might be acceptable for the time being; otherwise the change will become more intrusive. Note also that this brings the emitted data size of .ds.x vs .tfloat in line for non-ELF targets as well; the issue will be even more obvious when further taking into account a subsequent patch fixing .dc.x/.dcb.x (where output sizes currently differ depending on input format). Extend existing x86 testcases. |
