* XXX: we're cheating here in order to avoid creating object files
|
|
* for mfbt /just/ to provide a function like FatalError() to be used
|
|
* by MOZ_ASSERT(). (It'll happen eventually, but for just ASSERT()
|
|
* it isn't worth the pain.) JS_Assert(), although unfortunately
|
|
* named, is part of SpiderMonkey's stable, external API, so this
|
|
* isn't quite as bad as it seems.
|
|
*
|
|
* Once mfbt needs object files, this unholy union with JS_Assert()
|
|
* will be broken.
|
|
*
|
|
* JS_Assert is present even in release builds, for the benefit of applications
|
|
* that build DEBUG and link against a non-DEBUG SpiderMonkey library.
