+Subject: [PATCH 13/63] [Patch, microblaze]: Fixed missing save of r18 in
+ fast_interrupt. Register 18 is used as a clobber register, and must be stored
+ when entering a fast_interrupt. Before this fix, register 18 was only saved
+ if it was used directly in the interrupt function.
+
+However, if the fast_interrupt function called a function that used
+r18, the register would not be saved, and thus be mangled
+upon returning from the interrupt.
+
+Changelog

+Subject: [PATCH 17/63] [Patch, microblaze]: Add INIT_PRIORITY support Added
+ TARGET_ASM_CONSTRUCTOR and TARGET_ASM_DESTRUCTOR macros.
+
+These macros allows users to control the order of initialization
+of objects defined at namespace scope with the init_priority
+attribute by specifying a relative priority, a constant integral
+expression currently bounded between 101 and 65535 inclusive.
+
+Lower numbers indicate a higher priority.

+Changelog

+2013-11-26 Nagaraju Mekala <nagaraju.mekala@xilinx.com>

+Subject: [PATCH 22/63] [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 24/63] [PATCH] microblaze.md: Improve 'adddi3' and 'subdi3'
+ insn definitions Change adddi3 to handle DI immediates as the second operand,
+ this requires modification to the output template however reduces the need to
+ specify seperate templates for 16-bit positive/negative immediate operands.
+ The use of 32-bit immediates for the addi and addic instructions is handled
+ by the assembler, which will emit the imm instructions when required. This
+ conveniently handles the optimizable cases where the immediate constant value
+ does not need the higher half words of the operands upper/lower words.
+
+Change the constraints of the subdi3 instruction definition such that it
+does not match the second operand as an immediate value. This is because
+there is no definition to handle this case nor is it possible to
+implement purely with instructions as microblaze does not provide an
+instruction to perform a forward arithmetic subtraction (it only
+provides reverse 'rD = IMM - rA').

+Subject: [PATCH 27/63] [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.
+

+ * loop-invariant.c
+ (find_invariants_to_move): Add the logic of regs_used based
+ on liveness.

+Subject: [PATCH 30/63] [patch,microblaze]: Fix the calculation of high word in
+ a long long 6. .4-bit
+
+This patch will change the calculation of high word in a long long 64-bit.
+Earlier to this patch the high word of long long word (0xF0000000ULL) is
+coming to be 0xFFFFFFFF and low word is 0xF0000000. Instead the high word
+should be 0x00000000 and the low word should be 0xF0000000. This patch
+removes the condition of checking high word = 0 & low word < 0.
+This check is not required for the correctness of calculating 32-bit high
+and low words in a 64-bit long long.

+
+ [Patch, microblaze]: MB-64 removal of barrel-shift instructions from default
+ By default MB-64 is generatting barrel-shift instructions. It has been
+ removed from default. Barrel-shift instructions will be generated only if
+ barrel-shifter is enabled. Similarly to double instructions as well.

+ 17 14:11:00 2019 +0530
+
+ [Patch, microblaze]: MB-64 removal of barrel-shift instructions from default
+ By default MB-64 is generatting barrel-shift instructions. It has been
+ removed from default. Barrel-shift instructions will be generated only if
+ barrel-shifter is enabled. Similarly to double instructions as well.
