Chris Lattner 259df2bf3c Fix the llvm bootstrap

Chris Lattner 743dd2cd80 If errno is zero strerror_r does not modify the buffer, leaving it unterminated. 
This causes garbage to be printed out after error messages.

Reid Spencer 8d0f126b74 Make the check for global variables the same as the one for functions. In 
both cases they are looking for non-external variables/functions that do
not have internal linkage. Using "!isExternal()" is a little more
understandable than "hasInitializer()"

Chris Lattner 147c561432 Make sure to clear the LazyFunctionLoadMap after we ParseAllFunctionBodies. 
Otherwise, clients who call ParseAllFunctionBodies will attempt to parse
the function bodies twice, which is (uh) very very bad (tm).

This fixes gccld on python.

Chris Lattner 1b9f9c5f67 Do not put internal symbols into the symbol table. This shrinks the symbol 
table for archives in common cases, and prevents trying to resolve a
external reference with an internal reference.  This shrinks the libpython.a
symbol table from 126302 to 19770 bytes.

Chris Lattner 7b0fbe7ccf Correct the recursive PHI node handling routines in a way that CANNOT induce 
infinite loops (using the new replaceSymbolicValuesWithConcrete method).

This patch reverts this patch:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20050131/023830.html

... which was an attempted fix for this problem.  Unfortunately, that patch
caused test/Regression/Transforms/IndVarsSimplify/exit_value_tests.llx to fail
and slightly castrated the entire analysis.  This patch fixes it right.

This patch is dedicated to jeffc, for making me deal with this.  :)

Alkis Evlogimenos c4a44c6b3d Localize globals if they are only used in main(). This replaces the 
global with an alloca, which eventually gets promoted into a

Andrew Lenharth e0b789fdf5 so, if you beat on it, you too can talk emacs into having a sane indenting policy... Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)

Chris Lattner 4585abd549 If we have an indirect call site that calls N functions, inline the N functions 
into a temporary graph, remember it for later, then inline the tmp graph into
the call site.

In the case where there are other call sites to the same set of functions, this
permits us to just inline the temporary graph instead of all of the callees.

This turns N*M inlining situations into an N+M inlining situation.

Chris Lattner a1b39fa5ad * Make some methods more const correct. 
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists.
  This makes many operations on these lists much more natural, and avoids
  *exteremely* expensive copying of DSCallSites (e.g. moving nodes around
  between lists, erasing a node from not the end of the vector, etc).

With a profile build of analyze, this speeds up BU DS from 25.14s to
12.59s on 176.gcc.  I expect that it would help TD even more, but I don't
have data for it.

This effectively eliminates removeIdenticalCalls and children from the
profile, going from 6.53 to 0.27s.

Chris Lattner 800b72445f This file was schizophrenic when it came to representing sizes. In some 
cases it represented them as 'unsigned's, which are not enough for 64-bit
hosts.  In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.

This patch unifies all of the sizes to use size_t instead.

Chris Lattner be62e72273 Before doing expensive global analysis, check to make sure the pointer is 
not invalidated on entry and on exit of the block.  This fixes some N^2
behavior in common cases, and speeds up gcc another 5% to 22.35s.

Chris Lattner 787aed675d Eliminate generality that is not buying us anything. In particular, this 
will cause us to miss cases where the input pointer to a load could be value
numbered to another load.  Something like this:


  %X = load int* %P1
  %Y = load int* %P2

Those are obviously the same if P1/P2 are the same.  The code this patch
removes attempts to handle that.  However, since GCSE iterates, this doesn't
actually buy us anything: GCSE will first replace P1 or P2 with the other
one, then the load can be value numbered as equal.

Removing this code speeds up gcse a lot.  On 176.gcc in debug mode, this
speeds up gcse from 29.08s -> 25.73s, a 13% savings.
