this should work fine with thumb2 e.g. so this is a little broad brush here to diable it across

Why do you think that changing the instruction set (to thumb2) would make the JIT work any better?

If you tell me how, I'll test it on my i.MX6 (Cortex-A9) which is the platform that inspired the original bug report.

FWIW, I ran into this issue as well the first time I tried building webkitgtk with a compiler tuned for armv7a.

I did not try many variations but was able to build with a machine configuration with DEFAULTTUNE set to armv7ahf-neon (hard float with neon simd).

This link seems to also provide some more information on what configurations can be used to build webkitgtk on arm:

Assembler implementation for JIT has always worked better with thumb2.

Try adding

ARM_INSTRUCTION_SET_armv7a = “thumb"
ARM_INSTRUCTION_SET_armv7ve = “thumb"

in the webkitgtk recipe and see if it helps

this should work fine with thumb2 e.g. so this is a little broad brush here to diable it across
all armv7

Why do you think that changing the instruction set (to thumb2) would make the JIT work any better?

Assembler implementation for JIT has always worked better with thumb2.

If you tell me how, I'll test it on my i.MX6 (Cortex-A9) which is the platform that inspired the original bug report.

Try adding

ARM_INSTRUCTION_SET_armv7a = “thumb"
ARM_INSTRUCTION_SET_armv7ve = “thumb"

in the webkitgtk recipe and see if it helps

Hi,

To be clear, webkitgtk can build on armv7a, but doesn't work on runtime, cause displaying problems or ephiphany hang.

We are talking runtime here.

Sorry, still fails - tested on my i.MX6 target. Visiting www.google.com fails immediately. Looks like the JIT should be disabled for armv7
