-Subject: [PATCH] Fix the Microblaze crash with msmall-divides flag
-
-Fix the Microblaze crash with msmall-divides flag Compiler is crashing
-when we use msmall-divides and mxl-barrel-shift flag. This is because
-when use above flags microblaze_expand_divide function will be called
-for division operation. In microblaze_expand_divide function we are
-using sub_reg but MicroBlaze doesn't have subreg register due to this
-compiler was crashing. Changed the logic to avoid sub_reg call

-Subject: [PATCH] Inline Expansion of fsqrt builtin
-
-Inline Expansion of fsqrt builtin. The changes are made in the patch for
-the inline expansion of the fsqrt builtin with fqrt instruction. The
-sqrt math function takes double as argument and return double as
-argument. The pattern is selected while expanding the unary op through
-expand_unop which passes DFmode and the DFmode pattern was not there
-returning zero. Thus the sqrt math function is not inlined and expanded.
-The pattern with DFmode argument is added. Also the source and
-destination argument is not same the DF through two different
-consecutive registers with lower 32 bit is the argument passed to sqrt
-and the higher 32 bit is zero. If the source and destinations are
-different the DFmode 64 bits registers is not set properly giving the
-problem in runtime. Such changes are taken care in the implementation of
-the pattern for DFmode for inline expansion of the sqrt.

-Subject: [PATCH] MicroBlaze fix signed bit fields with bit field instructions
-
-The 'extv' definition is expected to sign extended the result based on
-the width of the bit field.
-
- https://gcc.gnu.org/onlinedocs/gccint/Standard-Names.html#index-extvm-instruction-pattern
-
-The MicroBlaze 'bsefi' instruction does not sign extended, it zero
-extends. There is no option for the instruction to sign extended the
-result and no simple instruction or expression to implement a variant
-length sign extend (only sext8/sext16 instructions exist).
-
-As such these definitions needs to be changed to the zero extended
-variant of 'extv' which is 'extzv'. This change updates the existing
-definitions to allow for signed bit fields to function correctly and be
-sign extended.

+Subject: [PATCH 22/54] [Patch,microblaze]: Inline Expansion of fsqrt builtin.
+ The changes are made in the patch for the inline expansion of the fsqrt
+ builtin with fqrt instruction. The sqrt math function takes double as
+ argument and return double as argument. The pattern is selected while
+ expanding the unary op through expand_unop which passes DFmode and the DFmode
+ pattern was not there returning zero. Thus the sqrt math function is not
+ inlined and expanded. The pattern with DFmode argument is added. Also the
+ source and destination argument is not same the DF through two different
+ consecutive registers with lower 32 bit is the argument passed to sqrt and
+ the higher 32 bit is zero. If the source and destinations are different the
+ DFmode 64 bits registers is not set properly giving the problem in runtime.
+ Such changes are taken care in the implementation of the pattern for DFmode
+ for inline expansion of the sqrt.
+

+Subject: [PATCH 23/54] [Patch] OPT: Update heuristics for loop-invariant for
+ address arithme. .tic.
+
+The changes are made in the patch to update the heuristics
+for loop invariant for address arithmetic. The heuristics is
+changed to calculate the estimated register pressure cost when
+ira based register pressure is not enabled. The estimated
+register pressure cost modifies the existing calculation cost
+associated to perform the Loop invariant code motion for address
+arithmetic.

+Subject: [PATCH 27/54] [Patch,rtl Optimization]: Better register pressure
+ estimate for loop . .invariant code motion
+
+Calculate the loop liveness used for regs for calculating the register pressure
+in the cost estimation. Loop liveness is based on the following properties.
+We only need to find the set of objects that are live at the birth or the header
+of the loop. We don't need to calculate the live through the loop by considering
+live in and live out of all the basic blocks of the loop. This is based on the
+point that the set of objects that are live-in at the birth or header of the loop
+will be live-in at every node in the loop.
+
+If a v live is out at the header of the loop then the variable is live-in at every node
+in the loop. To prove this, consider a loop L with header h such that the variable v
+defined at d is live-in at h. Since v is live at h, d is not part of L. This follows i
+from the dominance property, i.e. h is strictly dominated by d. Furthermore, there
+exists a path from h to a use of v which does not go through d. For every node p in
+the loop, since the loop is strongly connected and node is a component of the CFG,
+there exists a path, consisting only of nodes of L from p to h. Concatenating these
+two paths proves that v is live-in and live-out of p.
+
+Calculate the live-out and live-in for the exit edge of the loop. This patch considers
+liveness for not only the loop latch but also the liveness outside the loops.
