Simulation context switching is based on logic like setjmp and longjmp. This
|
|
context switching is only available for 32-bit targets. On 64-bit machines,
|
|
this context switching will fail.
|
|
|
|
The workaround on 64-bit machines for now is to build for a 32-bit target on the
|
|
64-bit machine. The workaround for this issue has been included in NuttX 6.15 and
|
|
beyond. For thoses versions, you must add SIM_M32=y to the .config file in
|
|
order to enable building a 32-bit image on a 64-bit platform.

---help---

Older versions of Cygwin toolsdecorated C symbol names by adding an
|
|
underscore to the beginning of the symbol name. Newer versions of
|
|
Cygwin do not seem to do this.
|
|
|
|
How do you know if you need this option? You could look at the generated
|
|
symbol tables to see if there are underscore characters at the beginning
|
|
of the symbol names. Or, if you need this option, the simulation will not
|
|
run: It will crash early, probably in some function due to the failure to
|
|
allocate memory.

|
|
The calling convention of the System V AMD64 ABI is followed on Solaris,
|
|
Linux, FreeBSD, Mac OS X, and other UNIX-like or POSIX-compliant operating
|
|
systems. The first six integer or pointer arguments are passed in registers
|
|
RDI, RSI, RDX, RCX, R8, and R9, while XMM0, XMM1, XMM2, XMM3, XMM4, XMM5,
|
|
XMM6 and XMM7 are used for floating point arguments. For system calls, R10
|
|
is used instead of RCX. As in the Microsoft x64 calling convention,
|
|
additional arguments are passed on the stack and the return value is stored
|
|
in RAX.
|
|
|
|
Registers RBP, RBX, and R12-R15 are callee-save registers; all others must
|
|
be saved by the caller if they wish to preserve their values.
|
|
|
|
Unlike the Microsoft calling convention, a shadow space is not provided; on
|
|
function entry, the return address is adjacent to the seventh integer argument
|
|
on the stack.

|

The Microsoft x64 calling convention is followed on Microsoft Windows and
|
|
pre-boot UEFI (for long mode on x86-64). It uses registers RCX, RDX, R8,
|
|
R9 for the first four integer or pointer arguments (in that order), and
|
|
XMM0, XMM1, XMM2, XMM3 are used for floating point arguments. Additional
|
|
arguments are pushed onto the stack (right to left). Integer return
|
|
values (similar to x86) are returned in RAX if 64 bits or less. Floating
|
|
point return values are returned in XMM0. Parameters less than 64 bits
|
|
long are not zero extended; the high bits are not zeroed.

config SIM_WALLTIME

---help---
|
|
NOTE: In order to facility fast testing, the sim target's IDLE loop, by default,
|
|
calls the system timer "interrupt handler" as fast as possible. As a result, there
|
|
really are no noticeable delays when a task sleeps. However, the task really does
|
|
sleep -- but the time scale is wrong. If you want behavior that is closer to
|
|
normal timing, then you can define SIM_WALLTIME=y in your configuration
|
|
file. This configuration setting will cause the sim target's IDLE loop to delay
|
|
on each call so that the system "timer interrupt" is called at a rate approximately
|
|
correct for the system timer tick rate. With this definition in the configuration,
|
|
sleep() behavior is more or less normal.
