| | | | | | | | | | | | | | | | The yasm/nasm preprocessor only checks the first token, which means that parameters such as `dword [rax]` are treated as identifiers, which is generally not what we want. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* | x86inc: Avoid using eax/rax for storing the stack pointerHenrik Gramner2017-01-09
| | | | | | | | | | | | | | | | | | When allocating stack space with an alignment requirement that is larger than the current stack alignment we need to store a copy of the original stack pointer in order to be able to restore it later. If we chose to use another register for this purpose we should not pick eax/rax since it can be overwritten as a return value.

| * x86inc: Add debug symbols indicating sizes of compiled functionsGeza Lore2016-01-23
| | | | | | | | | | | | | | | | | | | | | | Some debuggers/profilers use this metadata to determine which function a given instruction is in; without it they get can confused by local labels (if you haven't stripped those). On the other hand, some tools are still confused even with this metadata. e.g. this fixes `gdb`, but not `perf`. Currently only implemented for ELF. Signed-off-by: Anton Khirnov <anton@khirnov.net>
| * x86inc: Avoid creating unnecessary local labelsHenrik Gramner2016-01-23
| | | | | | | | | | | | | | | | | | | | | | | | The REP_RET workaround is only needed on old AMD cpus, and the labels clutter up the symbol table and confuse debugging/profiling tools, so use EQU to create SHN_ABS symbols instead of creating local labels. Furthermore, skip the workaround completely in functions that definitely won't run on such cpus. Note that EQU is just creating a local label when using nasm instead of yasm. This is probably a bug, but at least it doesn't break anything. Signed-off-by: Anton Khirnov <anton@khirnov.net>
