...n occur in other situations. I hope this addresses at least some of your questions. I am happy to continue this discussion if some questions remain or if you have new questions. --paulr From: Muhui Jiang [mailto:jiangmuhui at gmail.com] Sent: Tuesday, June 26, 2018 9:38 AM To: Robinson, Paul Cc: Yajin; llvm-dev Subject: Re: [llvm-dev] Instruction boundaries Hi Paulr I am using the llvm-dwarfdump. This is not the end of the function, thus there is no 'end_sequence' reported. Here I just want to give you an exception because you said that all the instructions should be listed inside dwar...

...reakpoint locations, and clearly you do not want to set breakpoints in data. Inline data is probably contained within the code ranges described in the DW_TAG_subprogram, however. --paulr From: Muhui Jiang [mailto:jiangmuhui at gmail.com] Sent: Tuesday, June 26, 2018 1:44 AM To: Robinson, Paul Cc: Yajin; llvm-dev Subject: Re: [llvm-dev] Instruction boundaries Hi Paulr According to my observation. Not all the instructions are listed in the line table. For example. We have address 0xa3a0 and 0xa3a4 as the instructions .text:0000A394 CMP R1, #0x42 .text:0000A398...

[RFC 0/3]: hvc_console rework for platform without hard irqs
This patch set if my first attempt to make virtio_console usable on s390. To do so, I had to change hvc_console, because s390 has no request_irq and no free_irq. I want to get feedback from the main users of hvc_console before I proceed. The basic idea of this patch set is to remove the calls to request_irq and free_irq and replace them with backend specific callbacks. Please see the
