4Subject: [PATCH 3/4] microblaze/sync.md: Correct behaviour and define
5 side-effects
6
7This change corrects the behaviour with regards to the bool output.
8Previously the definition would set the bool operand to true (non-zero)
9on failure, specifically at the 'cmp' against the expected operand which
10would be set non-zero when the memory != expected value. Instead of
11using the bool operand as the compare result use the clobbered %8
12operand for temporary comparison result and set the bool operand at the
13end of the definition to true (in this case the immediate value of 1).
14Also to ensure that the bool operand is 0 in all other cases the first
15instruction which is intended as a clear of the carry bit is reused to
16set the bool operand to 0 at the same time as clearing the carry bit.
17And finally the jump offsets were updated
18
19Additional to the behaviour change this change defines the side-effects
20of the atomic_compare_and_swap. Specifically the side effects where the
21bool and val operands are modified/set based on the value of the memory
22content. This prevents certain optimization behaviour from incorrectly
23optimizing away code. An example of this is the snippet below, where in
24certain cases the comparison is optimized away entirely.
25
26 mem = 2;
27 if (atomic_compare_and_swap(&mem, ...) == 2)
28 ...

4Subject: [PATCH] Fix the Microblaze crash with msmall-divides flag
5
6Fix the Microblaze crash with msmall-divides flag Compiler is crashing
7when we use msmall-divides and mxl-barrel-shift flag. This is because
8when use above flags microblaze_expand_divide function will be called
9for division operation. In microblaze_expand_divide function we are
10using sub_reg but MicroBlaze doesn't have subreg register due to this
11compiler was crashing. Changed the logic to avoid sub_reg call

4Subject: [PATCH] MicroBlaze fixed missing save of r18 in fast_interrupt
5
6Fixed missing save of r18 in fast_interrupt. Register 18 is used as a
7clobber register, and must be stored when entering a fast_interrupt.
8Before this fix, register 18 was only saved if it was used directly in
9the interrupt function.
10
11However, if the fast_interrupt function called a function that used
12r18, the register would not be saved, and thus be mangled
13upon returning from the interrupt.

5 TARGET_ASM_DESTRUCTOR macros.
6
7These macros allows users to control the order of initialization
8of objects defined at namespace scope with the init_priority
9attribute by specifying a relative priority, a constant integral
10expression currently bounded between 101 and 65535 inclusive.
11
12Lower numbers indicate a higher priority.

4Subject: [PATCH] Inline Expansion of fsqrt builtin
5
6Inline Expansion of fsqrt builtin. The changes are made in the patch for
7the inline expansion of the fsqrt builtin with fqrt instruction. The
8sqrt math function takes double as argument and return double as
9argument. The pattern is selected while expanding the unary op through
10expand_unop which passes DFmode and the DFmode pattern was not there
11returning zero. Thus the sqrt math function is not inlined and expanded.
12The pattern with DFmode argument is added. Also the source and
13destination argument is not same the DF through two different
14consecutive registers with lower 32 bit is the argument passed to sqrt
15and the higher 32 bit is zero. If the source and destinations are
16different the DFmode 64 bits registers is not set properly giving the
17problem in runtime. Such changes are taken care in the implementation of
18the pattern for DFmode for inline expansion of the sqrt.

4Subject: [PATCH] Update MicroBlaze ashlsi3 & movsf patterns
5
6This patch removes the use of HOST_WIDE_INT_PRINT_HEX macro in
7print_operand of ashlsi3_with_mul_nodelay,ashlsi3_with_mul_delay and
8movsf_internal patterns beacuse HOST_WIDE_INT_PRINT_HEX is generating
964-bit value which our instruction doesn't support so using gen_int_mode

18 ashlsi3_with_mul_delay,
19 movsf_internal):
20 Updated the patterns to use gen_int_mode function
21 * microblaze.c (print_operand):
22 updated the 'F' case to use "unsinged int" instead
23 of HOST_WIDE_INT_PRINT_HEX

6With this patch the loading of the DI mode immediate values will be
7using REAL_VALUE_FROM_CONST_DOUBLE and REAL_VALUE_TO_TARGET_DOUBLE
8functions, as CONST_DOUBLE_HIGH was returning the sign extension value
9even of the unsigned long long constants also

4Subject: [PATCH] Fix internal compiler error with msmall-divides
5
6This patch will fix the internal error microblaze_expand_divide function
7which comes because of rtx PLUS where the mem_rtx is of type SI and the
8operand is of type QImode. This patch modifies the mem_rtx as QImode and
9Plus as QImode to fix the error.

4Subject: [PATCH] Fix the calculation of high word in a long long 64-bit
5
6This patch will change the calculation of high word in a long long 64-bit.
7Earlier to this patch the high word of long long word (0xF0000000ULL) is
8coming to be 0xFFFFFFFF and low word is 0xF0000000. Instead the high word
9should be 0x00000000 and the low word should be 0xF0000000. This patch
10removes the condition of checking high word = 0 & low word < 0.
11This check is not required for the correctness of calculating 32-bit high
12and low words in a 64-bit long long.

6This patches adds new bsefi and bsifi instructions. BSEFI- The
7instruction shall extract a bit field from a register and place it
8right-adjusted in the destination register. The other bits in the
9destination register shall be set to zero BSIFI- The instruction shall
10insert a right-adjusted bit field from a register at another position in
11the destination register. The rest of the bits in the destination
12register shall be unchanged

4Subject: [PATCH] MicroBlaze fix signed bit fields with bit field instructions
5
6The 'extv' definition is expected to sign extended the result based on
7the width of the bit field.
8
9 https://gcc.gnu.org/onlinedocs/gccint/Standard-Names.html#index-extvm-instruction-pattern
10
11The MicroBlaze 'bsefi' instruction does not sign extended, it zero
12extends. There is no option for the instruction to sign extended the
13result and no simple instruction or expression to implement a variant
14length sign extend (only sext8/sext16 instructions exist).
15
16As such these definitions needs to be changed to the zero extended
17variant of 'extv' which is 'extzv'. This change updates the existing
18definitions to allow for signed bit fields to function correctly and be
19sign extended.
