In what cases, do we need to add those implicit arguments? If you had AL<def> = ... AH<def> = ... ... = AX you'd need implicit uses/defs to define AX.

Good day to all, Gert Hulselmans requested a feature for MDISKCHK.COM that would function roughly like GETARGS.COM[1] by Murali Krishnan Ganapathy: DOS SET command output for MEMDISK kernel arguments passed by previous boot-loaders. He also needed to support the case for MEMDISK-in-a-MEMDISK type situations, where all MEMDISK kernel arguments could be gathered together and output as a list

On several variants of x86 processors, mixing `ah`, `al` and `ax` as source/destination in the same dependency chain will have some penalties, so for THOSE processors, there is a benefit to NOT use `al` and `ah` to reflect parts of `ax` - I believe this is caused by the fact that the processor doesn't ACTUALLY see these as parts of a bigger register internal...

I'm trying to see how the x86 backend deals with the relationship between AL, AH and AX, but I can't get it to generate any code that would expose an interesting scenario. For example, I wrote this piece: typedef struct { char x, y; } struct_t; struct_t z; struct_t foo(char *p) { struct_t s; s.x = *p++; s.y = *p; z = s; s.x++; return s; } But the output...

...the struct, but the stores were still separate (even though storing CX would be correct)... Here's another question that falls into the same category: The function X86InstrInfo::loadRegFromStackSlot does not append any implicit uses/defs. How does it know that it won't need them? If AX was spilled in the middle of a live range of EAX, wouldn't restoring of AX need to implicitly define EAX? We deal with such cases a lot in the Hexagon backend and it continues to be a major pain. I'm trying to understand if there are better options for us. -Krzysztof On 5/24/2016...

In fact the other routines calling p...

...ze, the output is still the same. As per the subject, I'm not really interested in the quality of the final code, but in the way that the x86 target deals with the structural relationship between these registers. Specifically, I'd like to see if it would generate implicit defs/uses for AX on defs/uses of AH/AL. I looked in the X86 sources and I didn't find code that would make me certain, but I'm not too familiar with that backend. Having a testcase to work with would make it a lot easier for me. -Krzysztof On 5/24/2016 12:03 PM, mats petersson wrote: > On several...

How does it know that it won't need them? If AX was spilled in the middle of a live range of EAX, wouldn't restoring of AX need to implicitly define EAX? Doing that would say that we override the other lanes of EAX, which is not what we want. In what cases, do we need to add those implicit arguments? Also, IIRC, right now, even with sub re...
