97c18e7f0e Comment out a few unsafe replacement funcs. 2014-04-22 08:07:10 -07:00

7326c6e716 Fix a race condition on shutdown with hashmap. 
Also, always need to init the blocks, they are not zero initialized.

f35168e0e0 Hardcode a bunch of function hashes so we can replace them. 
Without needing an external file.

dde2f3ade6 Re-replace functions after loading a savestate. 
Might need to clear before saving too... anyway, this makes testing a bit
easier for certain areas.

Also, correctly decrease downcount on x86.

76e61e10a9 Fix hashmap crashes with games that load modules. 
This should properly unload and reload the functions as necessary.

eca06c60c7 Spend a bit less time in Read_Instruction on load. 2014-03-02 10:20:40 -08:00

8948990871 Optimize searching for existing symbols. 
Checking every time is slow, we should just skip by the address.  Some is
just the locking overhead.

7c2d36e802 Don't add to the symbol map what was found there. 
Wasn't hurting anything, but slight hit on performance.

26b4335637 Optimize symbol map in debug mode a bit more.

b1d6eefb8a Call UpdateActiveSymbols only once from MIPSAnalyst instead of for every recognized function. 
Reduces startup slowdown when using a function signature file drastically.

fe2b62c27d Make the "on change" checkbox for memchecks work. 
But, for now, only on sw and similar instructions, the rest don't work
yet and just always break.

76afb2a8d5 Avoid returning points from the symbol map. 
Now that it uses a lookup, this is even more dangerous.  But, the maps
could be reordered while it's trying to print the pointer and cause that
data to become invalid.

This should be safe from race conditions.

1abb001e7f Don't hashmap functions smaller than 16 bytes. 
Otherwise, small stub funcs "replicate" annoyingly.

bde1d14f25 Update hashmap before deciding to abort. 
Otherwise, if you delete it, it can never generate one.

Seeing a bunch of forwarders and stuff that won't hash safely.

2eab4aa1bf Play around with function replacement. Turned off by default of course. 2013-12-17 23:40:27 +01:00

2140892074 Initial preparations for ability to replace game functions with custom implementations. 
Also auto-saves hashmap additions and reapplies the hashmap on function
rename so that if you rename a function that exists in several copies
they will all be labelled.

Note that actual function replacement is not activated yet.

0636a65ad9 Use ReadEntireFile() a few more places. 
This fixes one or two minor memory leaks.

Unknown W. Brackets
735968ba9b Add a setting to maintain a global func hash map. 
This makes it easier to deal with functions that have a common
implementation between multiple games, e.g. libc funcs.

1bccfa4141 Look for downward jumps for elses when scanning. 
Otherwise, we often end the function earlier than it should be.

43be44947f Correctly reuse symbol map entries when scanning. 
Before we created one huge function in place of the old.
