However part of this optimization may introduce new + register usage, so it must be called before register allocation has + occurred. This means that this optimization is actually called + well before the optimization that reorders basic blocks (see + function above). + + This optimization checks the feedback information to determine + which basic blocks are hot/cold, updates flags on the basic blocks + to indicate which section they belong in. This information is + later used for writing out sections in the .o file. Because hot + and cold sections can be arbitrarily large (within the bounds of + memory), far beyond the size of a single function, it is necessary + to fix up all edges that cross section boundaries, to make sure the + instructions used can actually span the required distance. The + fixes are described below. + + Fall-through edges must be changed into jumps; it is not safe or + legal to fall through across a section boundary. Whenever a + fall-through edge crossing a section boundary is encountered, a new + basic block is inserted (in the same section as the fall-through + source), and the fall through edge is redirected to the new basic + block. The new basic block contains an unconditional jump to the + original fall-through target. (If the unconditional jump is + insufficient to cross section boundaries, that is dealt with a + little later, see below). + + In order to deal with architectures that have short conditional + branches (which cannot span all of memory) we take any conditional + jump that attempts to cross a section boundary and add a level of + indirection: it becomes a conditional jump to a new basic block, in + the same section. The new basic block contains an unconditional + jump to the original target, in the other section. + + For those architectures whose unconditional branch is also + incapable of reaching all of memory, those unconditional jumps are + converted into indirect jumps, through a register. + + IMPORTANT NOTE: This optimization causes some messy interactions + with the cfg cleanup optimizations; those optimizations want to + merge blocks wherever possible, and to collapse indirect jump + sequences (change "A jumps to B jumps to C" directly into "A jumps + to C"). Those optimizations can undo the jump fixes that + partitioning is required to make (see above), in order to ensure + that jumps attempting to cross section boundaries are really able + to cover whatever distance the jump requires (on many architectures + conditional or unconditional jumps are not able to reach all of + memory). Therefore tests have to be inserted into each such + optimization to make sure that it does not undo stuff necessary to + cross partition boundaries.

If a Joined argument can legitimately be omitted, specify -; "JoinedOrMissing" instead of "Joined".

It is possible that + the reference will be later optimized out. The call-graph is built + conservatively in order to make conservative data flow analysis possible. + + The callgraph at the moment does not represent indirect calls or calls + from other compilation unit.

The value of the +long double is the sum of the values of the two parts (except for +-0.0). The most significant part is required to be the value of the +long double rounded to the nearest double, as specified by IEEE. For +Inf values, the least significant part is required to be one of +0.0 +or -0.0. No other requirements are made; so, for example, 1.0 may be +represented as (1.0, +0.0) or (1.0, -0.0), and the low part of a NaN +is don't-care. + +Classification +-------------- + +A long double can represent any value of the form + s * 2^e * sum(k=0...105: f_k * 2^(-k)) +where 's' is +1 or -1, 'e' is between 1022 and -968 inclusive, f_0 is +1, and f_k for k>0 is 0 or 1. These are the 'normal' long doubles. + +A long double can also represent any value of the form + s * 2^-968 * sum(k=0...105: f_k * 2^(-k)) +where 's' is +1 or -1, f_0 is 0, and f_k for k>0 is 0 or 1. These are +the 'subnormal' long doubles. + +There are four long doubles that represent zero, two that represent ++0.0 and two that represent -0.0. The sign of the high part is the +sign of the long double, and the sign of the low part is ignored. + +Likewise, there are four long doubles that represent infinities, two +for +Inf and two for -Inf. + +Each NaN, quiet or signalling, that can be represented as a 'double' +can be represented as a 'long double'. In fact, there are 2^64 +equivalent representations for each one. + +There are certain other valid long doubles where both parts are +nonzero but the low part represents a value which has a bit set below +2^(e-105). These, together with the subnormal long doubles, make up +the denormal long doubles. + +Many possible long double bit patterns are not valid long doubles. +These do not represent any value. + +Limits +------ + +The maximum representable long double is 2^1024-2^918. The smallest +*normal* positive long double is 2^-968. The smallest denormalised +positive long double is 2^-1074 (this is the same as for 'double'). + +Conversions +----------- + +A double can be converted to a long double by adding a zero low part. + +A long double can be converted to a double by removing the low part. + +Comparisons +----------- + +Two long doubles can be compared by comparing the high parts, and if +those compare equal, comparing the low parts. + +Arithmetic +---------- + +The unary negate operation operates by negating the low and high parts. + +An absolute or absolute-negate operation must be done by comparing +against zero and negating if necessary. + +Addition and subtraction are performed using library routines. They +are not at present performed perfectly accurately, the result produced +will be within 1ulp of the range generated by adding or subtracting +1ulp from the input values, where a 'ulp' is 2^(e-106) given the +exponent 'e'. In the presence of cancellation, this may be +arbitrarily inaccurate. Subtraction is done by negation and addition. + +Multiplication is also performed using a library routine. Its result +will be within 2ulp of the correct result. + +Division is also performed using a library routine. Its result will +be within 3ulp of the correct result. diff --git a/contrib/gcc/config/rs6000/darwin-ldouble.c b/contrib/gcc/config/rs6000/darwin-ldouble.c index 210f2d6a331..c30a98cc90f 100644 --- a/contrib/gcc/config/rs6000/darwin-ldouble.c +++ b/contrib/gcc/config/rs6000/darwin-ldouble.c @@ -1,5 +1,6 @@ /* 128-bit long double support routines for Darwin. - Copyright (C) 1993, 2003, 2004, 2005 Free Software Foundation, Inc. + Copyright (C) 1993, 2003, 2004, 2005, 2006, 2007 + Free Software Foundation, Inc.
