Justine Tunney	5f4f6b0e69	Make _Thread_local work across platforms ... We now rewrite the binary image at runtime on Windows and XNU to change mov %fs:0,%reg instructions to use %gs instead. There's also simpler threading API introduced by this change and it's called _spawn() and _join(), which has replaced most clone() usage.	2022-07-10 04:01:17 -07:00

Justine Tunney	e466dd0553	Add torture test for zipos file descriptors ... This change hardens the code for opening /zip/ files using the system call interface. Thread safety and signal safety has been improved for file descriptors in general. We now document fixed addresses that are needed for low level allocations.	2022-06-15 16:29:49 -07:00
