Hi all,</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">

<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
In response to this issue[0] on Bugzilla, I recently committed changes to make assembly directives case insensitive for generic directives and their aliases[1], ARM[2] and AArch64[3]. (since those are the targets I have knowledge of)</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
<br>
</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
I realise this was probably a bit too hasty of me, so I'm writing this to gather feedback on how to proceed.</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">

<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Some concerns were raised that it may be easier to fix projects that aren't using lower case directives. My intent was more to remove our reliance on case in general, which is more an implementation detail than a feature as far as I can tell. Maybe this is
not a strong enough argument for change.</div>

<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
No target in llvm uses anything but lower case directives. Some targets supported by GCC/binutils do document mixed case directives, but accept any case.</div>

<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
So my questions for the list are:</div>
<div>
<ul>
<li><font color="#000000" face="Calibri, Arial, Helvetica, sans-serif"><span style="">do you agree with the changes so far? (happy to revert if not)</span></font></li><li><font color="#000000" face="Calibri, Arial, Helvetica, sans-serif"><span style=""><font color="#000000" face="Calibri, Arial, Helvetica, sans-serif"><span style="margin:0px">should the same changes be applied to other targets?</span></font><br>
</span></font></li><li><font color="#000000" face="Calibri, Arial, Helvetica, sans-serif"><span style="">could there be future situations where a target would need case specific directives?<br>
</span></font></li><li><font color="#000000" face="Calibri, Arial, Helvetica, sans-serif">Where should this behaviour (whatever it ends up as) be documented? I found [4] but it's more about extensions than the assembler as such.</font></li></ul>
</div>
