Chris Lattner e3fa5aa91c minor code cleanup
llvm-svn: 70361
2009-04-29 04:12:34 +00:00
Chris Lattner 7d10386113 Disable the load-shrinking optimization from looking at
anything larger than 64-bits, avoiding a crash.  This should
really be fixed to use APInts, though type legalization happens
to help us out and we get good code on the attached testcase at
least.

This fixes rdar://6836460

Daniel Dunbar c1b1658751 Add incredibly bare bones docs/tools.
- Mirroring LLVM's docs/CommandGuide, a place to put .pod files which
   are used to generate man/html/etc documentation for tools provided
   as part of clang.

Ted Kremenek 7686ffaf07 retain/release checker: Refactor the guts of getClassMethodSummary to not depend
on ObjCMessageExpr. This will enable us to use it elsewhere. This should not
change any functionality.

Bill Wendling 9f795134f3 The second part of the change from -fast to -O#. This changes the JIT to accept
an optimization level instead of a simple boolean telling it to generate code
"fast" or the other type of "fast".

llvm-svn: 70347
2009-04-29 00:32:19 +00:00
Bill Wendling 084669a1c9 Second attempt:
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

Dan Gohman ed7f3a0eec As with r70333, give the primary induction variable a use so
that it can't be trivially eliminated.

Dan Gohman 2625f2cb80 Make this testcase slightly less trivial, so that it doesn't fail
if indvars happens to optimize away the unused primary induction
variable.

Douglas Gregor b925652433 Optimize IdentifierInfo storage within the precompiled header. We've
now gotten back about 180k of the 500k we lost.

Douglas Gregor 1d583f2838 Implement a minor space optimization for the PCH identifier table,
which eliminates the storage for IdentifierInfo in the "uninteresting
identifier" cases. Sadly, this only brought back 7k of the 500k we
lost :(

Douglas Gregor e6648fb79e Implement checking for macro definitions that occur on the command
line when using a PCH that were not provided when building the PCH
file. If those names were used as identifiers somewhere in the PCH
file, reject the PCH file.

Douglas Gregor ab4df58193 Revert r70075 and r70078, which reorganized the PCH on-disk hash table
for identifiers to separate "interesting" from "uninteresting"
identifiers. However, to cope with compiler invocations where the
predefines buffers mismatch, we need to be able to search the complete
identifier table. Cocoa.h.pch is now about 500k larger that it used to
be :(

Daniel Dunbar fb83baaf76 With -ccc-pch-is-pch, always treat precompiled inputs as PCH,
regardless of extension.
 - Otherwise we can't expect that just plugging in -ccc-pch-is-pch
   will work.

Douglas Gregor c379c07240 Allow some differences between the predefines buffer used to build a
PCH file and the predefines buffer used when including the PCH
file. We (explicitly) detect conflicting macro definitions (rejecting
the PCH file) and about missing macro definitions (they'll be
automatically pulled from the PCH file anyway).

We're missing some checking to make sure that new macro definitions
won't have any impact on the PCH file itself (e.g., #define'ing an
identifier that the PCH file used).

Eli Friedman 4058a842e6 Fix a minor edge case in C89 mode related to the definition of a

right diagnostic there anyway.)

Ted Kremenek ce6b865c21 ccc-analyzer: Don't automatically generate 'Parser Rejects' files anymore. The
frontend is far enough along that most discrepancies between Clang and GCC are
(at least for C and Objective-C) are intentional. We also now have codegen to
test the frontend.

Jakob Stoklund Olesen fb9e23b217 Don't coalesce a physical register with an incompatible virtual register.
If the physical register does not belong to the virtual register's regclass,
don't coalesce. The physical register could be an invalid operand for an
instruction using the vreg.

The regclass matching is done after determining the actual subregisters being copied.
