DESCRIPTION:manyclangs is a database of compiler binaries for every LLVM co
 mmit\, stored at a fraction of the original storage cost. This is made pos
 sible by an efficient storage system fine-tuned for object code called elf
 shaker. It allows for a months' worth of LLVM builds to be packaged into o
 nly a few hundred MiB and for any build to be recovered in a matter of sec
 onds\, even on conventional hardware. This technology can substantially de
 crease the time to run any past build\, aiding in debugging\, for example\
 , bisecting a 2\,000-commit range in 20s. The low operational costs of man
 yclangs increase the probability the service can be available long-term\, 
 and make it possible to integrate within other systems\, for example to pr
 ovide a web-based compiler at any commit.

SUMMARY:Manyclangs: Fast bisection with a small storage cost
TRANSP:OPAQUE
X-ALT-DESC;FMTTYPE=text/html:<p>manyclangs is a database of compiler binari
 es for every LLVM commit\, stored at a fraction of the original storage co
 st. This is made possible by an efficient storage system fine-tuned for ob
 ject code called elfshaker. It allows for a months' worth of LLVM builds t
 o be packaged into only a few hundred MiB and for any build to be recovere
 d in a matter of seconds\, even on conventional hardware. This technology 
 can substantially decrease the time to run any past build\, aiding in debu
 gging\, for example\, bisecting a 2\,000-commit range in 20s. The low oper
 ational costs of manyclangs increase the probability the service can be av
 ailable long-term\, and make it possible to integrate within other systems
 \, for example to provide a web-based compiler at any commit.</p>
