8c95a221b0 7l: deal with huge (negative or > 24bit) register offsets, fix LACON, avoid DWORD in constant pool when we can sign extend 2019-04-17 23:43:59 +02:00

15c3f45e5f 7c: fix long to vlong/pointer conversion, avoid negative immediate offsets 
we have to explicitely convert to vlong by sign or
zero extending as not every operation leaves a proper
zero/sign extended result in the register. for example
NEGW will zero extend, breaking negative int offsets
on pointers.

we explicitely insert SXTW or MOVWU instructions which
the peephole optimizer takes out again when it is safe
todo so.

when promoting constant offsets to immediate offsets,
make sure the offset will be in range. otherwise the
linker will produce not so optimal pointer arithmetic
instructions to calculate the offset.

b44440bd16 devsd: fix sddelpart() AGAIN 
the previous "fix" missed to advance pp so after
we hit a invalid partition all following partitions
would be ignored.

6a3a3d69c6 bcm: add pl011 uart driver 
the raspi has two uarts, the pl011 and the mini. only one
can be used at a time due to pin muxing. the bcm kernel
uses the mini by default.

12fc1c7d3e 7l: fix bitcon instruction selection and encoding 
the possible bitmasks generated depend on the data width
of the instruction, so we introduce C_BITCON32 and C_BITCON64
operand types to keep them apart.

the encoding of the bitcon operation was wrong.

the temporary stack segment used to be at a fixed address above or
below the user stack. these days, the temp stack is mapped dynamically
by sysexec so TSTKTOP is obsolete.

2251ef7a32 sshnet: pass on open failure error message, simplify 
return the error message from MSG_CHANNEL_OPEN_FAILURE
in the "connect" control write.

use a extra state "Finished" to distinguish server from client
initiated teardown. that way we do not need to track if we
send the MSG_CHANNEL_CLOSE message in closeclient(). this way
we also cannot be fooled by misbehaving server.

simplify hangupclient() by removing state transitions and doing
them in the caller explicitely. that way we can use hangupclient()
instead of dialedclient().
