This patch removes the exisinting error_vreport() function and replaces it
with a more generic vreport() function that takes an enum describing the
information to be reported.
As part of this change a report() function is added as well with the
same capability.
To maintain full compatibility the
QEMU currently has a standard method to report errors with
error_repot(). This ensure a sane and standard format when printing
errors. This series is attempting to extend this functionality for
warnings and information as well.
At the moment only one error is being converted, I wanted to get the

This patch enables the indirect jump path using an LDR (literal)
instruction. It will be interesting to test and see which performs
better among the two paths.

We can use a branch to register instruction for exit_tb for offsets
greater than 128MB.

Hello,
The following patches enable us to relax the 128MB code buffer size
limitation on ARM64 hosts.
Patch 2 increases this limitation to 3GB, even though ADRP+ADD can
address 4GB of pc-relative addresses to give us some slack.
Patch 3 uses LDR (literal) to load the address, allowing us to remo

We use ADRP+ADD to compute the target address for goto_tb. This patch
introduces the NOP instruction which is used to align the above
instruction pair so that we can use one atomic instruction to patch
the destination offsets.
