This is a ~x86 package, but I thought it was worth the heads-up that if I decompile my DSDT and correct mistakes in order to recompile cleanly but then decompile and attempt to recompile this output again, the compiler throws errors. This suggests that the optimisation engine is being somewhat overzealous...
Created attachment 230595 [details] Original DSDT
Created attachment 230597 [details] DSDT.dsl corrected for errors This compiles with iasl-20100428 with 0 errors, 0 warnings, 0 remarks, and 1004 optimisations.

Interestingly, changing DSDT.dsl.2 as follows: --- DSDT.dsl.2.orig 2010-05-06 14:33:08.362849657 +0100 +++ DSDT.dsl.2 2010-05-06 14:33:18.282848521 +0100 @@ -18,8 +18,7 @@ */ DefinitionBlock ("DSDT.aml", "DSDT", 1, "CX700 ", "AWRDACPI", 0x00001000) { - External (LNK9) - External (\_SB_.PCI1.PCI0.LNK9) + External (\_SB_.PCI0.LNK9) Scope (_PR) { ... allows the table to be compiled again. Decompiling *this* output shows the only change to be the reversion of the above patch. (Compilation also succeeds if the "External (LNK9)" line is left in place - but its presence of absence doesn't seem to affect the outcome)
Can you include your emerge --info, so we know on what kind of system this occured? Also forwarding to maintainer.

Did older versions work fine?
Yup - all versions prior to sys-power/iasl-20100428 have worked without issus - so this is a new regression in the most recent (~x86/~amd64) version.
Is this still an issue with newer version of the package?
I'll check...
The second attachment ("DSDT.dsl corrected for errors") now compiles for the first time with: 0 Errors, 29 Warnings, 191 Remarks, 1004 Optimizations ... but when this is then de-compiled and re-compiled, the output is instead: 12 Errors, 19 Warnings, 167 Remarks, 53 Optimizations ... so the same 12 errors seem to have been injected by sys-power/iasl-20140214 as the 2010 version - it's just picker about what generates warnings. Additionally, with the 2014 version, if I take /sys/firmware/acpi/tables/DSDT for a running system, decompile it (-d), then re-compile it (-ts) I get 25 errors - although an output hex-file is still created, so 'error' appears to be non-fatal. Admittedly, this probably says more about motherboard manufacturers' (or indeed MSFT's) ability to code and/or follow documented standards than it does about Intel's tools...
can you check with sys-power/iasl-20180810?
