[Qemu-devel] [PATCH v1 0/4] arm semihosting cleanups

[Alex Bennée]

Hi,

One of the comments that came up during the review of the plugin
series was around the clumsiness of tweaking arm_ld*_code. The main
reason was it was being used to "peak" at semihosting instructions at
runtime to decide what to do. This series fixes that up to make all
the semihosting invocation consistent and resolved at translation
time.

Alex Bennée (4):
  target/arm: handle M-profile semihosting at translate time
  target/arm: handle A-profile T32 semihosting at translate time
  target/arm: handle A-profile A32 semihosting at translate time
  target/arm: remove run time semihosting checks

[Qemu-devel] [PATCH v1 1/4] target/arm: handle M-profile semihosting at translate time

[Alex Bennée]

We do this for other semihosting calls so we might as well do it for
M-profile as well.

No, I meant imm8 == 0xab.  And, sure, cleaning the other patches would be good.

This patch clashes with this one:
https://lists.gnu.org/archive/html/qemu-devel/2019-07/msg00343.html
that Peter already queued:
https://lists.gnu.org/archive/html/qemu-devel/2019-07/msg00692.html

Peter, if you want this for 4.1, it might be easier to dequeue "Restrict
semi-hosting to TCG", apply Alex series, and re-apply "Restrict
semi-hosting to TCG", the conflicts should be trivial (function name
changed check_for_semihosting -> handle_semihosting).

Thanks,

Phil.

This isn't 4.1 material - unless I can figure out the weird single-step
while semihosting bug.

Well I'm not sure it is ARM-specific... I remember something similar

Drop the inline, probably.

Since you are renaming away the "check", perhaps hoist

> +    if (cs->exception_index == EXCP_SEMIHOST) {

this check to the caller, change the return to void,

so we get

	if (cs->exception_index == EXCP_SEMIHOST) {
	    handle_semihosting(cs);
	    return;
	}
