https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91474 --- Comment #11 from Joey Dumont --- I can confirm that this revision fixes the issue. I'll try to lookout for the gcc-9 version where this will be released. Thank you!

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91474 --- Comment #9 from Dragan Mladjenovic --- Thanks for the confirmation. I've sent a request for backporting r273174 change onto gcc 9 branch. I believe this issue will be updated automatically when the backport lands.

I was meant to try this version for the target compiler, not the host compiler. I successfully built the target compiler (mips64-elf) with r273174. I changed the affected version to 9.2.0, as 9.1.0 was my host compiler, not the target compiler. I can test with 9.2.1 and other versions, if necessary.

--- Comment #6 from Joey Dumont ---
Sorry for the delay, had trouble setting up the test toolchain.
>From what I can see, this does not solve the issue. In fact, the generated
paralle_settings.ii is identical to the one generated before.
To test this, I compiled the d57faea9337 commit of gcc-git, which corresponds
to r273174 according to this commit message. I configured it with
--prefix=~/software-test/ and removed options with references to system
directories in the options listed above. Otherwise I kept the rest the same. To
compile the cross-compiler, I exported PATH and LD_LIBRARY_PATH, like so
export PATH="/home/valandil/software-test/bin:${PATH}"
export LD_LIBRARY_PATH="/home/valandil/software-test/lib:${PATH}"
and did the rest as usual.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91474 --- Comment #5 from Dragan Mladjenovic --- Hi, I wasn't able to reproduce this issue which leds me to believe that this is the r273174 is the probable fix. In either way, it should be backported to gcc-9 branch, but it would be nice if you can confirm if it fixes the problem. Thanks in advance.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91474 --- Comment #3 from Dragan Mladjenovic --- You can try manualy rerunning the faulting command after libtool: compile: ... with -save-temps.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91474 --- Comment #2 from Joey Dumont --- How do I pass -save-temps to make? Is there a environment variable that changes the gcc command options?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91474 Paul Hua changed: What|Removed |Added CC||paul.hua.gm at gmail dot com --- Comment #1 from Paul Hua --- The preprocessed file parallel_settings.ii of parallel_settings.cc should be provided. Look at this: https://gcc.gnu.org/bugs/ "the preprocessed file (*.i*) that triggers the bug, generated by adding -save-temps to the complete compilation command, or, in the case of a bug report for the GNAT front end, a complete set of source files (see below)."
