Rafael Espindola 4c70eeaf33 Make EmitIntValue more efficient and more like what we do for leb128. The
difference is much smaller (about 0.3s) but significant.

Rafael Espindola 675fbb2ad1 Do with uleb the same trick we now do with dwarf line/address advances. This
avoids creating leb128 fragments and speeds up the test in PR8711 to 33s.

Rafael Espindola 57ab708bdd Try to resolve symbol differences early, and if successful create a plain
data fragment. This reduces the time to assemble the test in 8711 from 60s to
54s.

Bill Wendling f0b36a3cfd The tLDR instruction wasn't encoded properly:
<MCInst 2251 <MCOperand Reg:70> <MCOperand Reg:66> <MCOperand Imm:0> <MCOperand Reg:0> <MCOperand Imm:14> <MCOperand Reg:0>>

Notice that the "reg" here is 0, which is an invalid register. Put a check in
the code for this to prevent crashing.

Devang Patel 5eed2e63f8 It may not be an option to skip .debug_line if there are file reference in already emitted debug info. So, for now, emit dummy line table entry to make older linker and assemblers happy. This is not a new behavior, original AsmPrinter emitted similar line table entries.

Rafael Espindola bf792065a9 Add a fast path to EvaluateSymbolicAdd. This avoids computing symbol addresses
which then avoids running EnsureValid.
This cuts the assembly time of the testcase in PR8711 from 2:50 minutes to 1
minute.

2010-12-02 05:44:06 +00:00
Rafael Espindola 60ebca9aaf The sections that the ELF object writer has to create are very simple and
contain only data. Handle them specially instead of using AddSectionToTheEnd.
This moves a hack from the generic assembler to the elf writer. It is also
a bit faster and should make other improvements easier.

Jakob Stoklund Olesen 4be0bd79a4 Implement the first half of LiveDebugVariables.
Scan the MachineFunction for DBG_VALUE instructions, and replace them with a
data structure similar to LiveIntervals. The live range of a DBG_VALUE is
determined by propagating it down the dominator tree until a new DBG_VALUE is
found. When a DBG_VALUE lives in a register, its live range is confined to the
live range of the register's value.

LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially
extended when registers are joined.

The missing half will recreate DBG_VALUE instructions from the intervals when
register allocation is complete.

The pass is disabled by default. It can be enabled with the temporary command
line option -live-debug-variables.

Duncan Sands c4fb38b821 I don't think it makes any sense to assert that the target supports SSE3 here.
The user (i.e. whoever generated a call to the intrinsic in the first place) is
essentially asking for a particular instruction to be placed in the assembler.
If that instruction won't execute on the target machine, that's their problem
not ours.  Two buildbots with processors that don't support SSE3 were barfing
on the apm.ll test in CodeGen/X86 because of this assertion.
