/* This file gives a basic initialisation of a Cortex-A series core. It is
the bare minimum required to get Cortex-A core running with a semihosting
interface.
It sets up a basic 1:1 phsyical address to virtual address mapping;
turns the MMU on; enables branch prediction; activates any integrated
caches; enables the Advanced SIMD and VFP co-processors; and installs
basic exception handlers.
It does not handle peripherals, and assumes all memory is Normal.
It does not change processor state from the startup privilege and security
level.
This has only been tested to work in ARM state.
By default it assumes exception vectors are located from address 0.
However, if this is not true they can be moved by defining the
_rdimon_vector_base symbol. For example if you have HIVECS enabled you
may pass --defsym _rdimon_vector_base=0xffff0000 on the linker command
line. */
/* __ARM_ARCH_PROFILE is defined from GCC 4.8 onwards, however __ARM_ARCH_7A
has been defined since 4.2 onwards, which is when v7-a support was added
and hence 'A' profile support was added in the compiler. Allow for this
file to be built with older compilers. */

! C run time start off
! This file supports:
!
! - both 32bit pointer and 64bit pointer environments (at compile time)
! - an imposed stack bias (of 2047) (at run time)
! - medium/low and medium/anywhere code models (at run time)
! Initial stack setup:
!
! bottom of stack (higher memory address)
! ...
! text of environment strings
! text of argument strings
! envp[envc] = 0 (4/8 bytes)
! ...
! env[0] (4/8 bytes)
! argv[argc] = 0 (4/8 bytes)
! ...
! argv[0] (4/8 bytes)
! argc (4/8 bytes)
! register save area (64 bits by 16 registers = 128 bytes)
! top of stack (%sp)
! Stack Bias:
!
! It is the responsibility of the o/s to set this up.
! We handle both a 0 and 2047 value for the stack bias.
! Medium/Anywhere code model support:
!
! In this model %g4 points to the start of the data segment.
! The text segment can go anywhere, but %g4 points to the *data* segment.
! It is up to the compiler/linker to get this right.
!
! Since this model is statically linked the start of the data segment
! is known at link time. Eg:
!
! sethi %hh(data_start), %g1
! sethi %lm(data_start), %g4
! or %g1, %hm(data_start), %g1
! or %g4, %lo(data_start), %g4
! sllx %g1, 32, %g1
! or %g4, %g1, %g4
!
! FIXME: For now we just assume 0.
! FIXME: if %g1 contains a non-zero value, atexit() should be invoked
! with this value.

; The state of all the registers (except for msp, chc and rab)
; is the same as when the process was interrupted.
;
; We must make the stack and window consistent before calling the handler
; The orignal rab value is on the stack. The interrupt handler placed
; rfb-Windowsize in rab. This is required to support nested interrupts.
;
; Note that the window becomes incosistent only during certain
; critical sections in spill, fill, longjmp and sigcode.
; rfb - rab > windowsize => we are in spill
; rfb - rab < windowsize => we are in fill
; gr1 + 8 > rfb => we are in long-longjmp case
; In case of spill, fill and lonjmp; rab is modified first,
; so if we are in one of these critical sections,
; we set rab to rfb - WINDOWSIZE.

/* The following functions are provided for software stack checking.
If hardware stack-checking is being used then the code can be
compiled without the PCS entry checks, and simply rely on VM
management to extend the stack for a thread.
The stack extension event occurs when the PCS function entry code
would result in a stack-pointer beneath the stack-limit register
value. The system relies on the following map:
+-----------------------------------+ <-- end of stack block
| ... |
| ... |
| active stack |
| ... | <-- sp (stack-pointer) somewhere in here
| ... |
+-----------------------------------+ <-- sl (stack-limit)
| stack-extension handler workspace |
+-----------------------------------+ <-- base of stack block
The "stack-extension handler workspace" is an amount of memory in
which the stack overflow support code must execute. It must be
large enough to deal with the worst case path through the extension
code. At the moment the compiler expects this to be AT LEAST
256bytes. It uses this fact to code functions with small local
data usage within the overflow space.
In a true target environment We may need to increase the space
between sl and the true limit to allow for the stack extension
code, SWI handlers and for undefined instruction handlers of the
target environment. */

@
@ The "current sl" is somewhere between "original sp" and "current sp"
@ but above "true sl". The "current sl" should be at least 256bytes
@ above the "true sl". The 256byte stack guard should be large enough
@ to deal with the worst case function entry stacking (160bytes) plus
@ the stack overflow handler stacking requirements, plus the stack
@ required for the memory allocation routines.
@
@ Normal PCS entry (before stack overflow check) can stack 16
@ standard registers (64bytes) and 8 floating point registers
@ (96bytes). This gives a minimum stack guard of 160bytes (excluding
@ the stack required for the code). (Actually only a maximum of
@ 14standard registers are ever stacked on entry to a function).
@
@ NOTE: Structure returns are performed by the caller allocating a
@ dummy space on the stack and passing in a "phantom" arg1 into
@ the function. This means that we do not need to worry about
@ preserving the stack under "sp" even on function return.
@
@ Code should never poke values beneath sp. The sp register
@ should always be "dropped" first to cover the data. This
@ protects the data against any events that may try and use
@ the stack.
SUB ip, sp, ip @ extra stack required for function
@ Add stack extension code here. If desired a new stack chunk
@ can be allocated, and the register state updated suitably.
@ We now know how much extra stack the function requires.

! C run time start off
! This file supports:
!
! - both 32bit pointer and 64bit pointer environments (at compile time)
! - an imposed stack bias (of 2047) (at run time)
! - medium/low and medium/anywhere code models (at run time)
! Initial stack setup:
!
! bottom of stack (higher memory address)
! ...
! text of environment strings
! text of argument strings
! envp[envc] = 0 (4/8 bytes)
! ...
! env[0] (4/8 bytes)
! argv[argc] = 0 (4/8 bytes)
! ...
! argv[0] (4/8 bytes)
! argc (4/8 bytes)
! register save area (64 bits by 16 registers = 128 bytes)
! top of stack (%sp)
! Stack Bias:
!
! It is the responsibility of the o/s to set this up.
! We handle both a 0 and 2047 value for the stack bias.
! Medium/Anywhere code model support:
!
! In this model %g4 points to the start of the data segment.
! The text segment can go anywhere, but %g4 points to the *data* segment.
! It is up to the compiler/linker to get this right.
!
! Since this model is statically linked the start of the data segment
! is known at link time. Eg:
!
! sethi %hh(data_start), %g1
! sethi %lm(data_start), %g4
! or %g1, %hm(data_start), %g1
! or %g4, %lo(data_start), %g4
! sllx %g1, 32, %g1
! or %g4, %g1, %g4
!
! FIXME: For now we just assume 0.
! FIXME: if %g1 contains a non-zero value, atexit() should be invoked
! with this value.

! Fast SH memcpy
!
! by Toshiyasu Morita (tm@netcom.com)
! hacked by J"orn Rernnecke (joern.rennecke@superh.com) ("o for o-umlaut)
! SH5 code Copyright 2002 SuperH Ltd.
!
! Entry: ARG0: destination pointer
! ARG1: source pointer
! ARG3: byte count
!
! Exit: RESULT: destination pointer
! any other registers in the range r0-r7: trashed
!
! Notes: Usually one wants to do small reads and write a longword, but
! unfortunately it is difficult in some cases to concatanate bytes
! into a longword on the SH, so this does a longword read and small
! writes.
!
! This implementation makes two assumptions about how it is called:
!
! 1.: If the byte count is nonzero, the address of the last byte to be
! copied is unsigned greater than the address of the first byte to
! be copied. This could be easily swapped for a signed comparison,
! but the algorithm used needs some comparison.
!
! 2.: When there are two or three bytes in the last word of an 11-or-more
! bytes memory chunk to b copied, the rest of the word can be read
! without side effects.

location into the cache, it just allocates a cache line and zeros
it out. This means that if you do not write to the entire cache
line before writing it out to memory some data will get zero'ed out
when the cache line is written back to memory and data will be lost.

do prefetches on cache lines that are not going to be completely written.

* Using PREFETCH_HINT_LOAD_STREAMED instead of PREFETCH_LOAD on load
* prefetches appears to offer a slight preformance advantage.
*
* Using PREFETCH_HINT_PREPAREFORSTORE instead of PREFETCH_STORE
* or PREFETCH_STORE_STREAMED offers a large performance advantage
* but PREPAREFORSTORE has some special restrictions to consider.
*
* Prefetch with the 'prepare for store' hint does not copy a memory
* location into the cache, it just allocates a cache line and zeros
* it out. This means that if you do not write to the entire cache
* line before writing it out to memory some data will get zero'ed out
* when the cache line is written back to memory and data will be lost.
*
* Also if you are using this memcpy to copy overlapping buffers it may
* not behave correctly when using the 'prepare for store' hint. If you
* use the 'prepare for store' prefetch on a memory area that is in the
* memcpy source (as well as the memcpy destination), then you will get
* some data zero'ed out before you have a chance to read it and data will
* be lost.
*
* If you are going to use this memcpy routine with the 'prepare for store'
* prefetch you may want to set USE_MEMMOVE_FOR_OVERLAP in order to avoid
* the problem of running memcpy on overlapping buffers.
*
* There are ifdef'ed sections of this memcpy to make sure that it does not
* do prefetches on cache lines that are not going to be completely written.
* This code is only needed and only used when PREFETCH_STORE_HINT is set to
* PREFETCH_HINT_PREPAREFORSTORE. This code assumes that cache lines are
* 32 bytes and if the cache line is larger it will not work correctly.

/* This deals with the o32 FPXX and FP64 cases. Here we must use
SDC1 and LDC1 to access the FPRs. These instructions require
8-byte aligned addresses.
Unfortunately, the MIPS jmp_buf only guarantees 4-byte alignment
and this cannot be increased without breaking compatibility with
pre-existing objects built against newlib. There are 11 GPRS
saved in the jmp_buf so a buffer that happens to be 8-byte aligned
ends up leaving the FPR slots 4-byte aligned and an (only) 4-byte
aligned buffer leads to the FPR slots being 8-byte aligned!
To resolve this, we move the location of $31 to the last slot
in the jmp_buf when the overall buffer is 8-byte aligned. $31
is simply loaded/stored twice to avoid adding complexity to the
GPR_LAYOUT macro above as well as FPR_LAYOUT.
The location of the last slot is index 22 which is calculated
from there being 11 GPRs saved and then 12 FPRs saved so the
index of the last FPR is 11+11.
The base of the jmp_buf is modified in $4 to allow the
FPR_OFFSET macros to just use the usual constant slot numbers
regardless of whether the realignment happened or not. */
