Description Richard Ash 2020-11-15 17:10:10 UTC 
dev-lang/spidermonkey-78.4.1 ebuild has the line CHECKREQS_DISK_BUILD="5600M" which means that emerge checks for 5.6GB of free space before starting the build. Unfortunately the amd64 build needs considerably more space than this to complete successfully

Reproducible: Always

Steps to Reproduce:
1. Clear 5.6GB of portage temp directory space.
2. Emerge dev-lang/spidermonkey-78.4.1 on amd64 stable 
dev-lang/spidermonkey-78.4.1:78::gentoo [60.5.2_p0-r4:60::gentoo] USE="jit -debug -lto% -test (-custom-cflags%) (-custom-optimization%) (-minimal%) (-system-icu%*)"
Actual Results:  
Emerge fails during install phase, no space left on device.
Note in this case the file system is genuinely full and not out of inodes, so this is not #753428.

Expected Results:  
Emerge completes successfully.

After the failure, the reported usage is 5.9GB:
$ sudo du -hs /var/tmp/portage/dev-lang/spidermonkey-78.4.1/
5.9G    /var/tmp/portage/dev-lang/spidermonkey-78.4.1/

Subsequent attempts (clearing more space each time and running `ebuild merge`) failed at 6.0 and 6.5GB. Making available a further 900MB then allowed the install phase to complete. The install phase alone seems to need ~2GB of free space on top of what is used by compilation. The messages:
 * Final size of build directory: 5797028 KiB (  5.5 GiB)
 * Final size of installed tree:   870872 KiB (850.4 MiB)
are misleading about this.

Free space in the build directory after successful build was 7.4GB. I would suggest this is a better value for the free space check in the ebuild.
