+ Code used some assumptions about type aliasing that might not hold for
all systems
expose sqrt2025-04-01T19:16:25ZKimplulkimi.h.kuparinen@gmail.com2025-04-01T19:16:25Zurn:sha1:478c92b425eca53a0d884fb8f5dea8d769016858
+ Requires linking with libm in some cases, which is fine I suppose, but
kind of annoying
handle immediates a bit better2025-03-26T11:17:58ZKimplulkimi.h.kuparinen@gmail.com2025-03-26T11:17:58Zurn:sha1:67a13eb82534996fbd6ba2fc0c36d3e1284bcd8e
+ Passing floats as immediate values is not supported in lightening, but
I might have a go at adding it since it seems like a useful feature at
some point
experiment with allocating regs on stack in interp2025-03-15T11:16:54ZKimplulkimi.h.kuparinen@gmail.com2025-03-15T11:16:54Zurn:sha1:912c07167705613c6db70e542723c7ec2c06c7ea
+ Avoids having to lug around an execution context, arguably simplified
things but now there's no real way to detect when we run out memory
for regs.

+ Still linear, but orders regs by some kind of priority
+ Use all registers available, not just callee-save
make code a bit more robust2025-03-07T16:52:54ZKimplulkimi.h.kuparinen@gmail.com2025-03-07T16:50:34Zurn:sha1:ba9145b0b7af2a82c62f8dfa28807958af5d0c8d
+ Should be more difficult to make mistakes in the future, ejit can now
automatically keep track of how many register slots are used and if 64
bit mode is required. Slight runtime overhead, but not too bad.
